6, with a fixed bolt hole, easy to install
7, small size: 3.2cm x 1.4cm PCB
8, using a wide voltage LM393 comparator

Module instruction

1, thermal resistance module is very sensitive to the environment temperature, generally used to detect the temperature of the surrounding environment;
2, through regulation of the potentiometer, can change the temperature detection threshold (i.e., control temperature value), such as the need to control the ambient temperature is 50 degrees modules in the corresponding environmental temperature transferred to the green light, dissolved oxygen (do) then the output low level, below the setting temperature value, the output high level, the green light does not shine.
3, DO output can be directly connected with the MCU, through the microcontroller to detect high and low level, which is to detect the temperature changes in the environment;
4, DO output can be directly driven by the shop relay module, which can be composed of a temperature control switch, control the operating temperature of the equipment, can also be used to heat the cooling fan, etc.;
5, the module of the temperature detection range of 20-80 degrees Celsius; 5, the module temperature detection range of 20-80 degrees celsius;
6, the module can also be replaced with a wired temperature sensor for water temperature, water tank, etc.;
7, small analog output AO can be connected to our AD module, through the AD conversion, can obtain more accurate numerical temperature
