Digital Humidity Sensor with Digital Temperature Output
|MEAS announces the HTU21D sensors are dedicated humidity and temperature plug and play transducers for OEM applications. Direct interface with a micro-controller is made possible as both the humidity and temperature sensor modules have digital outputs. HTU21D sensors feature low power consumption and are designed for high volume and cost sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip - which can be read out by command. Furthermore, the resolution of the HTU21D sensor can be changed by command (8/12bit up to 12/14bit for RH/T), low battery can be detected and a checksum improves communication reliability. Typical applications are automotive, medical, printers and humidifiers.
Summary of Features
- Full interchangeability with no calibration required in standard conditions
- Instantaneous desaturation after long periods in saturation phase
- Compatible with automatized assembly processes, including Pb free and reflow processes
- Individual marking for compliance to stringent traceability requirements
