MQ-9 Gas Leakage Detection Sensor

Gas Sensor(MQ9) module is useful for gas leakage detection (in home and industry). It is suitable for detecting LPG, CO, CH4. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer.

LM35 Temperature Sensor

Description The LM35 series are precision integrated-circuit temperature sensors, with an output voltagelinearly proportional to the Centigrade temperature. Thus the LM35 has an advantage over linear temperature sensors calibrated in ° Kelvin, as the  user is not required to subtract a large constant voltage from  the output to obtain convenient...

TTP229 8 Channel Digital Capacitive Switch Touch Sensor Module for Arduino

The TTP229 is capacitive sensing design specifically for touch pad controls. The device has a built in regulator for the touch sensor. Stable sensing method can cover diversity conditions. Interface control panel links through non-conductive dielectric material. The main application is focused at replacing of the mechanical switch or button.

Waterproof DS18B20 Digital Thermal Probe or Sensor

This is a pre-wired and waterproofed version of the DS18B20 sensor. Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances!
