1 PC MRTD-3011 Digital Thermopile Temperature Sensor
MRTD-3011 is a non-contact type digital thermopile sensor with I2C output. The thermopile chip 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. This sensor can be working in the temperature range of -10~85℃, and can measure during the range of -20~+250℃. 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 Power management system Temperature measurement and control of Home appliances (air conditioners, hair dryers, hoods, etc.) Interactive power control Lighting unit control Features TO-39 metal package, small viewing angle; Full integrated digital infrared thermopile; I2C output with internal temperature compensation; 2.6V to 5.5V single power supply for continuous operation; Signal sampling speed settable: adjustable 16-step speed (0.02Hz~2KHz); Good stability and wide working temperature range: -10~85℃; Built-in high-precision 20 Bit sigma delta ADC, ENOB up to 16 bits; Temperature measurement range: -20~+250℃; Temperature measurement accuracy: ±1℃ for below 100℃ range; ±2% for over 100℃; Chip sleep mode current 2μA @ 25°C/VDD=3V; Specifications Parameter Unit Min Typical Max Sensitive area of thermopile mm2 / 0.7x0.7 / Field of view Degree 54 Power supply range V 2.6 5.5 Power current Ua / / 300 Working temperature range ℃ -20 / +85 Storage temperature range ℃ -40 / +125 ESD rated power V / ±4000 / Filter wavelength range um 5.5 / 14 Temperature measurement range ℃ -20 250 Temperature measurement accuracy ℃ / ±1℃ for below 100℃ range;±2% for over 100℃ / * The description and specifications might be changed without notice.
