The Qwiic Module for Tessel 2 connects the I2C bus (GND, 3.3V, SDA, and SCL) on the Tessel 2 to the SparkFun Qwiic system. Just plug the modu...

The QTR-1A reflectance sensor carries a single infrared LED and phototransistor pair in an inexpensive, tiny 0.5" x 0.3" module that can be mounted...

This is an edge detection sensor from DFRobot. It will help your robot detect the edge of a precipice, preventing it from falling off a table...

A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It's an ideal for monitoring an urban garden, or you...

This Digital LED Voltmeter measures the voltage at a particular point of the system it has been hooked up to and then provides a readout on its thr...

This is a cool touch sensor from DFRobot. You can hook it up to the IO Expansion shield (for arduino) directly. It includes a metallic tape w...

You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize "Uh oh, this chip has ...

We took the Micro OLED and encapsulated it to make it water-resistant. Why? So your fish can watch TV. The Qwiic Water-Resistant OLED is a smal...

This type of photoresistor is made of environment-friendly materials(no Cadmium and Lead) compared with the traditional CDS photoresistor. It chan...
