ISB TS45D Infrared Thermopile Sensor | Contactless Temperature
ISB TS45D Infrared Thermopile Sensor – Contactless Temperature Measurement
The ISB TS45D is an infrared thermopile sensor designed for accurate non-contact temperature measurement. It converts thermal radiation from an object into a digital signal via I2C interface, making it ideal for embedded projects, industrial monitoring, and DIY electronics. With a wide measurement range and compact form factor, it delivers reliable readings without physical contact.

Compatibility
This sensor works with any microcontroller supporting I2C, such as Arduino Uno, ESP32, ESP8266, and Raspberry Pi. The 3.3V–5V tolerant logic levels eliminate level shifting on most boards. Pair it with a microcontroller and a small display for immediate readouts.
Wiring Notes
Connect VCC to 3.3V or 5V, GND to ground, SDA to analog pin A4 (Arduino Uno) or GPIO21 (ESP32), and SCL to A5 or GPIO22. Most I2C libraries enable internal pull-ups, but add 4.7kΩ pull-up resistors on SDA and SCL if communication is unstable.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino boards?
Yes, the ISB TS45D uses I2C and works directly with Arduino Uno, Nano, and Mega. Use the Wire library for communication.
Can it measure human body temperature accurately?
It can if calibrated and used at a consistent short distance (1–2 cm). Accuracy is within ±0.5°C, suitable for screening but not medical diagnosis.
What is the field of view and how does it affect measurements?
The sensor has a 90° field of view, meaning it averages temperatures over a wide area. For spot measurements, bring it closer to the target.
