Measuring sensors

Single point thermopile sensors

These sesnors are recomended if only one spot hast to be measured

• MLX90615
• MLX90614
• ZPT-115M

Thermopile array

These sensors scan several spots

• Grid eye
• TPA81

Smartphone IR cameras

• iPhoneX infrared cameras
• Flir One

Aiming (How to ensure the sensor measures the right spot)

• face tracing
• ultrasonic distance measureing
• a mirror with a contour. If your face fits in your foreheard is at the right position.
• scan a larger area and output the maximum

Trigger(how to start a measurement)

• Continuous time tagged trigger
• face detection
• temperature sensor reading
• can we use the same sensors that are in automatic doors? or in paper towel dispensers?
