This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO concentrations anywhere from 20 to 2000ppm.
This SparkFun breakout board houses the Honeywell's HIH-4030 humidity sensor. The HIH-4030 measures relative humidity (%RH) and delivers it as an analog output voltage.
This unit is used in a variety of industrial applications such as computer server systems and web application control systems.
Simple breakout board for the SparkFun MQ-3, MQ-4, MQ-6 and MQ-7 gas sensors.
The Teensy Prop Shield is a wonderfully full-features sensor add-on for Teensy (and other) microcontrollers, featuring 11 sensor inputs, audio amplification and 8MB extra memory.
A simple but effective Grove water sensor. Expose the electrodes to a drop of water, and the signal drops very low. Can be used with both analog and digital ports.
Measure temperature and humidity with the pre-calibrated Grove TempHumi sensor.
For more precise environmental measurements using the Grove system.
For simple and easy temperature measurement using the 1-wire protocol with a prepared DS18B20 sensor.
Thermocouples are widely used to measure extreme temperatures impossible to measure with other types of sensors.
