Notice: The new tracking number for China Post Ordinary Small Packet Plus only can track it have been ship out of China, not more Tracking information ,even it arrived or not . Please do not freeloaders,if you can not accept without more tracking information . Please choose China Post Air Mail if you want a full tracking info. Tracking info of China Post Ordinary Small Packet Plus can be check here : www.17track.net/en Uses: Temperature detection, temperature control sensors , ambient temperature detection Module Features : 1, using the NTC thermistor sensor , good sensitivity 2 , the comparator output signal is clean, good waveform , driving ability , more than 15mA. 3 , adjust the temperature distribution position detection threshold 4 , the working voltage 3.3V-5V 5, the output format : digital switching outputs ( 0 and 1 ) 6 , a fixed bolt holes for easy installation 7 , a small PCB board size : 3.2cm x 1.4cm 8 , using a wide voltage LM393 comparator Module for use 1 , the thermal resistance of the module is very sensitive to the ambient temperature , typically for detecting the temperature of the surrounding environment ; 2 , through the potentiometer adjustment, you can change the temperature detection threshold ( ie, control temperature ) , such as the need to control the ambient temperature is 50 degrees , the module in the corresponding ambient temperature to its green light , DO high power output when flat , set the temperature below this value, the output is high , the green light does not shine ; 3, DO output can be directly connected to the microcontroller through the microcontroller to detect high and low , thereby detecting temperature changes in the environment ; 4, DO output of the relay module can directly drive the shop , which can be composed of a thermostat to control the temperature of work -related equipment can also be connected to the cooling fan , etc. ; 5, the temperature detection range of the modules 20 to 80 ° C ; 6 , the module can be replaced with a line of temperature sensors used to control the water temperature , water and the like.
