Review on Temperature Controller Thermostat Waterproof Programmable by Ahmed Jackson

if you cannot calibrate the temperature sensor. what shoud that? no instructions, no data from the manufacturer and no way to calibrate the actual sensor. Setting the temperature is easy, adjusting the temperature sensor to reality is a non-existent feature. the inability to calibrate (or lack of calibration instructions renders it useless. The ability to calibrate any type of sensor is very important these days and the inability or lack of instructions renders this article useless. My advice, which you are welcome to take to the want to sell world?, some sort of instruction manual is included, even Chinese would be better than nothing that comes in the kit.
