This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 prov...

Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote contr...

Current transformers (CTs) are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building...

Features: Dimensions: 32 x 24 x 27H mm Voltage: 5-12VDC Output: 3.3V TTL Detection Distance: 3-7m (approx, adjustable) Delay Time: 5-200s (adjus...

The LM335A is a very easy-to-use analog temperature sensor. The LM335A works like a Zener diode with a breakdown voltage proportional to absolut...

A simple flex sensor 4.5" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - t...

This small digital distance sensor detects objects between 2 and 10 cm (0.8" and 4") away. With its quick response time, small size, and low cur...

The AM2302 is a wired version of the DHT22, in a large plastic body. It is a basic, low-cost digital temperature and humidity sensor. It uses a cap...

This is a 12-step rotary encoder with a nice 'clicking' feel. It's breadboard friendly, and has a pretty handy select switch (by pushing in on the ...

This is a simple to use PIR motion sensor with Grove compatible interface. Simply connect it to Stem shield and program it, when anyone moves in i...

This board is a simple carrier of Allegro's ±30A ACS714 Hall effect-based linear current sensor, which offers a low-resistance (~1.2 mΩ) current...

Melexis' MLX90614ESF-BAA is an infrared thermometer designed for non-contact temperature sensing. An internal 17-bit ADC and a powerful DSP contri...

Rotary encoders are used similarly to potentiometers. They're different from potentiometers in that an encoder has full rotation without limits....

Simple breakout board for the MQ - 3, MQ - 4, MQ - 6 and MQ - 7 gas sensors. All you need is VCC at 5V, GND, and a resistor to an ADC, that is it....
