Description
The digital thermopile sensor is an infrared thermopile temperature sensor packaged in TO39, eliminating direct contact with the object during measurement. It features an integrated I2C interface for communication with various application interfaces. Unlike conventional thermopile temperature sensors that only output voltage signals, this device incorporates an infrared thermopile, temperature compensation resistors, and an ASIC chip. The thermopile operates on the Seebeck effect, where dozens or hundreds of thermocouple pairs are connected in series through MEMS technology. These thermocouples absorb infrared radiation from the object, generating a voltage difference between the cold and hot ends. The built-in temperature compensation resistor continuously monitors internal temperature to ensure accurate compensation. Through the ASIC's algorithm and calibration process, the voltage signal is converted into a corresponding temperature signal, enabling rapid and precise temperature detection. Capable of operating within a wide temperature range of-10°C to +65°C and testing temperatures from-20°C to +250°C, this sensor offers extensive application potential.

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory, but the module will be calibrated before leaving the factory.
However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
