10 pcs MRT511/MRT311 Thermopile Temperature Sensor

[shortdesc]Application:Non-contact temperature measuring,Human presence detection...Feature:TO-46 metal package,High sensitivity,Quick response, Good stability,High filter transmittance,High precision NTC[/shortdesc]Production Description:MRT-511 thermopile sensor is based on MEMS technology, consists of hundreds of thermocouples connected in series. Using Seebeck principle, when there is a temperature difference between the target and the environment, the sensor gives the corresponding voltage output, therefore detecting the existence of the target or the temperature of the target.Feature: TO-46 metal package High sensitivity Quick response, Good stability High filter transmittance High precision NTC Application: Non-contact temperature measuring Infrared thermometer, such as ear temperature and forehead temperature measurement Continuous temperature control of production process Household appliances (Microwave oven, hair dryers, air conditioners etc), intelligent temperature induction and control system Human presence detection Main technical parameters: Parameter Value Unit Remarks Sensitive area 1.6×1.6  mm   Field of view 105  Degree Above 50% Thermopile resistor 120±30  KΩ 25℃ Noise voltage 45 nV/Hz1/2 25℃ Noise equivalent power 0.27 nW/Hz1/2 500K, 1Hz, 25℃ Response rate 124 V/W 500K, 1Hz, 25℃ Time constant 10 ms   Detection rate 1.0 ×108  cmHz1/2/W 500K, 1Hz, 25℃ NTC resistance 100 ±1％ KΩ 25℃ NTC(β) 3950 ± 1％ / 25℃/50℃ Working temperature -30 ~ 125℃
