Sensors

The PiicoDev Precision Temperature Sensor features a low-power, high precision TMP117 with 16-bit resolution and an accuracy of ±0.1°C (across -20°C to +50°C) with no calibration required.

The PiicoDev® Ambient Light Sensor is a great solution for sensing ambient light levels.

The PiicoDev® Distance Sensor is a long-distance laser-ranging sensor that uses Time-of-Flight (ToF) to accurately measure distances up to 4m.

When this motion sensor module is used in projects it can detect motion based on changes in infrared light in the environment. It is ideal to detect if a human has moved in or out of the sensor range. An LED will light up when movement is detected. This makes the module a great addition to security application projects. 

This rain sensor board detects moisture and can be used for triggering a relay buzzer or fan. TTL level output. Output drops low when rain is detected. 100mA output. Adjustable sensitivity. Rain sensor board 50L x 35Wmm. 5V input.

The transmitter module of the KEYES laser transmitter is designed for Arduino. Its connection port is compatible with the Arduino Shield transmitter.

A non-contact normally open switch which operates via a nearby magnetic field. Connects to a digital input on an Arduino board.
