Thermal Thermistor Temperature Sensor Module

Product DescriptionOperating voltage 3.3V-5V The output format: digital switching outputs (0 and 1) A fixed bolt holes for easy installation A small PCB board size: 3.2cm x 1.4cm Using a wide voltage LM393 comparatorThe switch is a spring-type, non-directional vibration sensor trigger switch can be triggered at any angle; The switch is in the OFF state still is open, when subjected to external vibration touch to achieve the appropriate force,or moving speed reaches the appropriate from the (partial) effort, conductive pin will generate an instant turn-on was an instant ON state; when the external force when disappears, switch back to the OFF state open; The switch all the materials used are environmentally friendly raw materials, in line with ROHS requirements; Under normal use, switch life of up to 20 million times; Applies to toys, burglar alarm, electronic scales, instruments, shoes, lights, gift lights, digital, sports equipment and other products; The trigger switch for low current control circuitThrough 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 output low when flat, set the temperature below this value, the output is high, the green light does not shine; The temperature detection range of the modules 20 to 80°C; The module can be replaced with a line of temperature sensors used to control the water temperature, water tanks, etc. Small plates AO analog output modules can be connected and shop AD by AD conversion, more accurate values ??can be obtained ambient temperature
