This magical cells based on the Peltier effect are capable of generating electric power. The SP1848-27145 40x40mm Thermoelectric Power Generator TEG 120°C Peltier Module operates maximum up to 120°C which will give you different voltage and current outputs at different values of temperature.

Thermoelectric Power Generators also are known as TEG or Peltier Module create a detects temperature differential on each side. You can take the advantage of this temperature differential detection to generate electricity.

After applying the heat on one side and cold on other side the device will start generating the voltage which depends upon the value of applied heat. The SP1848-27145 40x40mm Thermoelectric Power Generator TEG 120°C Peltier Module will generate the moderate amount of voltage with mA of current.

A Thermoelectric Generator (TEG) module is a semiconductor-based electronic component that functions as a small generator.
