A PIR (passive infrared) motion sensor is a device that detects physical movement within its field of vision by sensing changes in infrared radiation. This sensor works on the principle of detecting thermal thermal signals emitted by objects, mainly warm-blooded creatures like humans. The “passive” in the name refers to the fact that the sensor itself does not emit or radiate any energy for detection.

Easily connects to Dasduino/Arduino via digital pin. When it detects movement, it sets the output digital pin to HIGH. The angle that the sensor “sees” is 100 degrees and reaches up to 5 meters. It has a potentiometer for delay (how often to check for movement).

It is often used in a variety of applications, including home security systems, automatic lighting, and energy management, among others.

The hall effect sensor (Hall Effect sensor) will be able to detect the magnetic field in its vicinity thanks to the aforementioned physical law. A magnetic field that can be created by a magnet, a current flowing through a conductor or some third source, the Hall effect sensor will recognize each. This sensor has a programmed threshold at which it will change the state of its output signal, so it is a sensor with a digital output.

It measures moisture and outputs the data to the simple sensor that reads it. The simple sensor comes with easyC connectors onboard, which enables quick and easy connection with Dasduino microcontroller boards.

With the easy-to-use simple rain sensor, farmers can save water in irrigation. The sensor will alert them to shut down the water supply when it senses rain. It can even act as an automatic on and off switch, like turning on wipers on a car when it senses rain.

The Simple Light Sensor Board is a versatile solution for adding light detection to your electronics projects. It’s a complete module that provides both analog and digital outputs, giving you the flexibility to create a wide range of applications. Whether you’re building an automatic lighting system, a plant-monitoring device, or a smart home alarm, this sensor board provides the reliable light detection that every maker needs.

The onboard LM393 comparator and adjustable potentiometer make this board perfect for creating precise light-activated triggers. You can easily set a specific light threshold for the digital output, allowing you to trigger an action when the light level crosses a certain point. This is ideal for beginners who want a simple on/off signal, as well as for advanced users who need to fine-tune the sensor’s sensitivity for their specific application. Perfect for students learning about sensors, hobbyists building interactive projects, or engineers prototyping new devices.

What makes this light sensor board special is its all-in-one design, combining a LDR with all the necessary circuitry on a compact module.

On this module, there is a component, a phototransistor, which is capable of detecting infrared radiation. Since fire emits a large amount of infrared radiation, this sensor will detect it, but that is not its only application. Wherever there are IR (infrared) waves, this sensor will detect them, including from solar radiation.

The simple sensor has easyC connectors, which enables quick and easy connection with Dasduino microcontroller boards.

Light is one of the most important things in the life of most living beings. This is why it is common to work with light sensors when learning about electronics. A simple light sensor has a light dependent resistor (LDR) and sensor on a breakout board for easy wiring. The simple sensor comes with easyC connectors onboard, which enables quick and easy connection with Dasduino microcontroller boards.

As the name suggests, an LDR will change its resistance depending on the amount of light it is exposed to. The amount of light and resistance are inversely proportional. The more light it is exposed to, the less resistance it will have. So if there is more light, the board will have a resistance of several hundred Ohms. If the resistor is in the dark, it will have a resistance of several thousand Ohms.

How many times have you watered your plants and feared you’re overdoing it? With the simple soil humidity sensor, those worries are a thing of the past! This two-part sensor is straightforward to use. The two exposed prongs go into the soil and send the humidity information to the sensor via the connected wire. The more water is in the ground, the better the results will be.

The two pieces are connected with the provided JST-SH 2-pin cable. The sensor uses the LM393 differential comparator. The main benefit of this board is ability to give analog and digital output. By setting the potentiometer on the board, you are able to get digital signal at the DO pin when signal crosses certain value, while analog values will be present on the AO pin at all times.

Water is essential for life on Earth. Using water efficiently is very important. With the easy-to-use simple rain sensor, farmers can save water while irrigating their crops.

That’s possible thanks to the integrated controller inside the LED itself!

This module allows you to connect a Dasduino, or similar microcontroller, to a RS-485 communication protocol. The RS-485 is used to send data over long distances (up to 1200m) at 20Mbps and in high-noise environments, such as industrial. The module works on 5V and requires between 120μA and 500μA of current.

The RS-232 is a standard and very popular protocol for communication between two devices. It is a full-duplex protocol which means it can receive and send data at the same time, and data is sent at voltages from + 3V to + 15V for a digital “one” and from -3V to -15V for digital “zero”. This provides a more secure environment for data transmission which is resistant to noise or interference, which is why the RS-232 is often used in industry. This module converts serial communication to RS232.

Ever wanted to build your own weather station using Arduino? Then the BMP180 breakout board with precision sensor from Bosch might interest you. The digital sensor on the board precisely measures the changes in barometric pressure and temperature. It uses the piezoresistive effect to gather the information. Since the pressure varies depending on height, the sensor can measure altitude too. Very low current consumption and voltage allow this type of sensor to be used in many modern devices.

The design is 5V ready with an onboard regulator for 3.3V. The breakout board’s standard current consumption is very low, only 5 µA. It uses an I2C interface, and the I2C address is 0x77. No soldering, nor need for distinguishing between SDA and SCL is required due to easyC. The sensor has integrated EEPROM memory with data for calibration. The pressure is measured in steps of 1hPa (=0.01hPa =0,01mbar), and 0.1°C for temperature.

Product usage tips:

If there is an error while using the breakout board, see if it’s connected properly. Take a look at the pinout. If everything is properly connected, check if the I2C address of the breakout board is correct prior to programming it. The I2C 7-bit address should be 0x77. If everything is correctly connected and the I2C address is right, look through your code once again. There might be some bugs in the code that are stopping the sensor from working as it should.

BMP180 breakout board works very well in combination with any Dasduino board and OLED I2C 0.96” display breakout board. All of them use easyC so they can be connected in a matter of seconds. The BMP180 sensor can measure the barometric pressure and temperature, while the OLED display can show them. The breakout board also comes with two mounting holes so you can attach it onto something and it won’t budge.

To keep the sensor working for a long while, we would advise you not to use it in extreme conditions. Going over or below the temperature range will surely damage the sensor. Same with the pressure. Keep track of the current going through it. Allowing too high of a current through the breakout board will burn the sensor and render it completely useless.
