DS18B20 Temperature Sensor waterproof 1M, range: 55 C to ...

A waterproofed version of DS18B20 digital thermometer which provides 912 bits Celsius temperature measurements. The DS18B20 communicates over a 1 Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. Usable with systems. The cable is jacketed in PVC so we suggest keeping it under 100 degree C.

MQ 2 Gas Sensor IoCT

sensor is at working temperature and the platinum wires and SnO 2 form the sensing system. When the gas interacts with the sensor, the heat from the system ionizes the gas. This ionization allows SnO 2 to absorb the gas. This adsorption causes a change in the resistance on the sensor.
