Contactless Measurement OMRON MEMS
Thermal Sensors are able to detect the
slightest temperature changes

  • MEMS Thermal (IR sensor) measures the surface temperature of objects without touching them when the thermopile element absorbs the amount of radiant energy from the object.

Product Structure

OMRON's unique MEMS technology allows combining thermopile elements and ASICs into one package, resulting in ultra-compact footprint and high precision.

  • Infrared ray : Silicon lens far-infrared focusing -> MEMS thermopile Electromotive force occurrence -> ASIC Low noise amplifiere -> MCU A/D conversion, calculation, I2C and I/F Detect wavelengths in the range 8-12 ­m
  • MEMS thermopile detection principle : The sensor utilizes the seebeck effect in which thermoelectric force is generated due to the temperature difference that occurs across the junction points of two different types of metal.

Comparison with Pyroelectric Sensor

Both the pyroelectric sensor and non-contact MEMS thermal sensor can detect even the slightest amount of radiant energy from objects such as infrared radiation and convert them into temperature readings. However, unlike pyroelectric sensor that relies on motion detection, non-contact MEMS thermal sensor is able to detect the presence of stationary humans (or objects).

Pyroelectric sensor
Converts temperature readings only when detecting “temperature changes in the radiant energy” in its field of view.
Able to detect both stationary and motion state of humans (objects).
Able to detect both stationary and motion state of humans (objects).
MEMS thermal sensor (thermopile)
Converts temperature readings by “continuously detecting the temperature of radiant energy” in its field of view
Unable to detect stationary human (object) presence
Able to detect both stationary and motion state of humans (objects).

Safety Precautions

Precautions for Correct Use

Installation
  • The Sensor may not achieve the characteristics given in this datasheet due to the ambient environment or installation location. Before using the Sensor, please acquire an adequate understanding and make a prior assessment of Sensor characteristics in your actual system.
Operating Environment
  • Do not use the Sensor in locations where dust, dirt, oil, and other foreign matter will adhere to the lens. This may prevent correct temperature measurements.
  • Do not use the Sensor in any of the following locations.

    • Locations where the Sensor may come into contact with water or oil.
    • Outdoors
    • Locations subject to direct sunlight.
    • Locations subject to corrosive gases (in particular, chloride, sulfide, or ammonia gases).
    • Locations subject to extreme temperature changes.
    • Locations subject to icing or condensation.
    • Locations subject to excessive vibration or shock.
Noise Countermeasures
  • The Sensor does not contain any protective circuits. Never subject it to an electrical load that exceeds the absolute maximum ratings for even an instance. The circuits may be damaged. Install protective circuits as required so that the absolute maximum ratings are not exceeded.
  • Keep as much space as possible between the Sensor and devices that generates high frequencies (such as high-frequency welders and high-frequency sewing machines) or surges.
  • Attach a surge protector or noise filter on nearby noise-generating devices (in particular, motors, transformers, solenoids, magnetic coils, or devices that have an inductance component).
  • In order to prevent inductive noise, separate the connector of the Sensor from power lines carrying high voltages or large currents. Using a shielded line is also effective.
  • If a switching requlator is used, check that malfunctions will not occur due to switching noise from the power supply.
Handling
  • This Sensor is a precision device. Do not drop it or subject it to excessive shock or force. Doing so may damage the Sensor or change its characteristics. Never subject the connector to unnecessary force. Do not use a Sensor that has been dropped.
  • Take countermeasures against static electricity before you handle the Sensor.
  • Turn OFF the power supply to the system before you install the Sensor. Working with the Sensor while the power supply is turned ON may cause malfunctions.
  • Secure the Sensor firmly so that the optical axis does not move.
  • Install the Sensor on a flat surface. If the installation surface is not even, the Sensor may be deformed, preventing correct measurements.
  • Do not install the Sensor with screws. Screws may cause the resist to peel from the board. Secure the Sensor in a way that will not cause the resist to peel.
  • Always check operation after you install the Sensor.
  • Use the specified connector (GHR-04 from JST) and connect it securely so that it will not come off. If you solder directly to the connector terminals, the Sensor may be damaged.
  • Make sure to wire the polarity of the terminals correctly. Incorrect polarity may damage the Sensor.
  • Never attempt to disassemble the Sensor.
  • Do not use the cable harness to the other product.
