Boardoza TPiS 1T 1386 L5.5 H Thermopile Sensor Breakout Board

The Boardoza TPiS 1T 1386 L5.5 H Breakout Board is a non-contact infrared temperature sensor board designed for makers, developers, and embedded system enthusiasts who need accurate temperature measurements without physical contact. It uses the Excelitas TPiS 1T 1386 L5.5 H thermopile sensor to measure object temperature in a fast, hygienic, and contactless way, making it ideal for projects where traditional contact sensors are not suitable.

The onboard sensor provides strong thermal stabilization, ensuring reliable and consistent measurements even under harsh or changing environmental conditions. Communication is handled via the I²C interface, allowing easy integration with popular development platforms such as Arduino, ESP32, and Raspberry Pi. This breakout board is well suited for maker projects and prototypes including non-contact thermometers, industrial temperature monitoring, HVAC systems, smart home applications, medical devices, and general IoT-based temperature sensing solutions.
