Description
The digital thermopile sensor is a TO39 packaged infrared thermopile temperature sensor that does not require direct contact with the object being measured when measuring the temperature of the object. It comes with an I2C interface for various application interfaces to communicate with the sensor. Compared to conventional thermopile temperature sensors that only output voltage signals, their internal integration includes infrared thermopiles, temperature compensation resistors, and ASIC chips. Thermopile is based on Seebeck principle and is formed by connecting dozens or hundreds of pairs of thermocouples in series through MEMS technology. The thermopile absorbs infrared energy radiated from the measured object, generating a corresponding voltage difference at the cold and hot ends; The built-in temperature compensation resistor can sense the internal temperature of the sensor at any time to achieve temperature compensation; Through the built-in algorithm and calibration process of ASIC, the voltage signal can be converted into a corresponding temperature signal, enabling the sensor to quickly and accurately detect the temperature of the target. The sensor can be used in the range of 10℃ to +85℃, and the test temperature range is - 20~+250℃, which has widely application filed.

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.
