Outline
MMS702 is an infrared sensor using MEMS thermopile technology. It is a multi-pixel type with an array of eight elements arranged in a single row, and can acquire temperature in each angular region divided over a wide range of angles. This sensor can measure surface temperature of objects without touching them by capturing infrared radiation from the objects. The product outputs digital values of surface temperature of objects. I2C is adopted for the interface. Temperature of the sensor itself can also be measured.
Applications
Home electric appliances (refrigerator, air conditioner, microwave oven, etc.), Detection of human body, gestrure and other contactless temperature monitoring.
Features
(1)Low noise level
- Noise-equivalent temperature difference (NETD): below 0.06℃
(2) Eight elements in a single row, so pinpoint temperatures can be acquired over a wide angle.
- Viewing angle: over 50 degrees (5.5 degrees per element)
(3) Temperature value is directly available.
- Digital output of temperature values compensated by ambient temperature. Easy for rapid application engineering.
(4) Easily mountable with a connector.
- No need to prepare dedicated board for the sensor.
(5) Good temperature accuracy.
- High temperature accuracy using unique calibration technology
