1 PC MRT311S Thermopile Temperature Sensor
MRT-311 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. 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 Features TO-46 metal package High sensitivity Quick response, Good stability High filter transmittance High precision NTC Specifications Parameter Value Unit Remarks Chip size 1.1×1.1 mm / Field of view 95 Degree Above 50% Thermopile resistor 90±30 KΩ 25℃ Noise voltage 38 nV/Hz1/2 25℃ Noise equivalent power 0.23 nW/Hz1/2 500K, 1Hz, 25℃ Response rate 160±40 V/W 500K, 1Hz, 25℃ Temperature coefficient of resistance 0.06 %/℃ 25℃~75℃ Time constant ≤13 ms Detection rate 1.5 ×108 cmHz1/2/W 500K, 1Hz, 25℃ NTC resistance 100 ±0.5％ KΩ 25℃ NTC(β) 3950 ± 1％ / 25℃/50℃ Working temperature -30 ~ 125℃ * The description and specifications might be changed without notice.
