Finding themselves with electric heaters with useless thermostats, the people at foulab needed a better way to keep the heaters on and control the temperature. Instead of running mains leads around their apartment, they modified an X10 protocol wireless controller with some Arduino-compatible hardware and an external temperature sensor to build an intelligent thermostat that can control the heater in place.

... or our HUMID: Humidity and Temperature sensor module based on the popular DHT22 sensor unit. Both modules are fully documented and easy to get started with. These are only two of over a dozen of our sensor and outputs modules.
