Temperature Sensor Digital, Infrared (IR) -40°C ~ 85°C 16 b TO-39 (EU Version)

 Description

The digital temperature sensor in the Infrared (IR) TO-39 package is a high-precision sensing solution. Designed for applications where accurate, contactless temperature measurement is essential. Operating across a wide range of -40°C to 85°C, this sensor delivers stable and reliable readings even in demanding environments. Moreover, because it uses infrared detection, it measures temperature without physical contact. Which makes it ideal for moving objects, sensitive materials, and environments where hygiene and safety are priorities.

In addition, one of the key strengths of this IR-based digital temperature sensor is its fast response time. It quickly detects changes in surface temperature and then translates them into precise digital output.

Furthermore, with its 16-bit resolution, it ensures fine measurement accuracy, enabling developers to build systems that depend on consistent thermal feedback.

The sensor’s TO-39 metal can package also provides durability, thermal stability, and excellent protection against external interference. Because of this rugged construction, the digital temperature sensor performs reliably in harsh or fluctuating environments. Consequently, it can be used in factories, labs, medical facilities, and outdoor installations without losing performance.

Integration

Integration is equally simple due to the sensor’s digital interface. It connects easily to microcontrollers and development platforms such as Arduino, ESP32, STM32, and Raspberry Pi.

Additionally, the digital output eliminates the need for complex calibration circuits, allowing engineers to reduce design time and improve system accuracy. This ease of integration is especially helpful in compact or battery-powered devices where efficiency matters.

In practical applications, the digital temperature sensor is widely used in thermal scanners, smart thermostats, industrial machinery monitoring, food-processing equipment, and non-contact temperature control systems. Its ability to measure without touching the surface not only reduces contamination risks, but also enables safer operation in medical and industrial settings.

Overall, this infrared digital temperature sensor in a TO-39 package is a powerful, reliable, and versatile solution for modern temperature-sensing needs. Therefore, its precision, durability, and easy integration make it ideal for a broad range of engineering and automation projects.
