· The Grid-EYE sensor is a thermal infrared detector consisting of 64 thermopile elements arranged in a specific grid format. The Grid-EYE sensor is able to detect moving object, motionless object and also the direction of movements. The Grid-EYE sensor provides the temperature data of a human present at stationary as well as moving position.
infrared human sensors. Due to its principle of detecting change components of infrared radiation, a pyroelectric sensor can detect movement of a human while it loses measurement signals when he/she does not move. On the contrary, an MEMS Thermal sensor using thermopiles can retain measurement signals even if the human does not move.
· The ability to detect motionless people thanks to the use of thermopile-based sensors, unlike pyroelectric sensors that can only detect people when they are moving. Improved accuracy of detection of people's positions within the target space with thermal sensing possible over a two-dimensional 256 pixel (16x16 element) area.
Utilization of Thermopile sensor at an early stage of human detection is challenging as there are many things that produce thermal heat other than human such as electrical appliances and animals.
Furthermore, this method of sensing can also detect events such as a person walking past the doorway to a room, lingering outside, and entering or leaving the room.

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).
· The thermocouple inside a thermopile sensor is embedded over a silicon chip which makes the system extremely sensitive and accurate. Using the MLX90247 Thermopile Sensor. The IC MLX90247 is an excellent example of a versatile thermopile sensor device which can be ideally used for making a thermal scanner device or a contactless thermometer device.
So, each object emits infrared waves depending on its heat, and these waves are detected using a thermopile which get hotter and hotter, in the same time converting the excess heat to electricity, you can learn more if you want read this Article. Here are some information about the MLX 90614 sensor:
This document is intended to provide an introduction toutilizing thermopile sensors for contactless temperature measurement. Thermopiles are mainly used for contactless temperature measurement in a wide range of applications. Their primary function is to transfer the heat radiation emitted from objects into a voltage output.

· Abstract: This paper presents a simple approach to detect people using an 8times1 thermopile array sensor. The performance of the sensor is evaluated in terms of detection rates and false positives obtained in the application of the sensor to people counting at doorways and pedestrian detection from a mobile robot in a real environment. To ensure that people is detectable regardless of …
· Unlike typical pyroelectric human presence sensors that rely on motion detection, the D6T thermal sensor is able to detect the presence of stationary humans by detecting body heat, and can therefore be used to switch off unnecessary lighting, air conditioning, etc automatically when people are not present (regardless of whether they move or not). As the D6T sensors are also able to monitor the ...
