Environmental Sensors

MinebeaMitsumi offers cost effective environmental sensors in a miniaturized surface mount platform for applications requiring low power consumption, small size, and fast response time. Our temperature switches are available with hysteresis function ideal for consumer electronics over-heating protection. These sensors are available with either analog or digital output (I2C) for monitoring applications. We also offer a dual temperature and humidity sensor that employs a proprietary polymer and parallel plate capacitive structure provides robustness and reliability.

Applications:

  • Cameras
  • Laptops
  • Smart watch
  • Mobile device
  • Thermostat
  • Refrigeration
  • Environmental monitoring equipment

Features:

  • Digital I2C or Analog
  • Surface mount device
