MRT-511 Thermopile temperature sensor
Product description
MRT-511 type sensor is a thermopile temperature sensor, based on MEMS process, hundreds of thermocouples are connected in series. Using Seebeck's principle, when there is a temperature difference between the target and the environment, the sensor outputs a corresponding voltage, thereby detecting the presence or temperature of the target.
Sensor characteristics
TO-46 package, high sensitivity; fast response; good stability; high filter transmittance; high NTC accuracy.
Main application
1. Non-contact temperature measurement;
2. Infrared thermometers such as ear temperature and forehead temperature; u Continuous temperature control of the production process;
3. Temperature measurement and control of household appliances (microwave ovens, hair dryers, air conditioners, etc.);
4. Human presence detection.
