JOY-IT SEN-IR-TEMP modulo sensore di temperatura a infrarossi senza contatto (MLX90614) per Arduino, Raspberry Pi, ESP32, ESP8266

The JOY-IT SEN-IR-TEMP stands out with its Melexis MLX90614 infrared sensor, offering non-contact temperature measurement from -70°C to +380°C with medical-grade accuracy of ±0.5°C in the 0-50°C range. Unlike simple thermistors, it reads object temperature without physical contact, making it ideal for moving parts, hazardous materials, or hygiene-sensitive applications.

Highlights

• Non-contact infrared temperature sensing with 90° field of view
• Wide object temperature range: -70°C to +380°C
• Medical-grade accuracy: ±0.5°C (0-50°C), ±1°C full range
• High resolution: 0.02°C
• I2C interface for easy integration with Arduino, Raspberry Pi, ESP32, ESP8266
• Factory calibrated with adjustable emissivity
• Low power consumption: ~1.5 mA
• Reverse polarity protection

In daily use

Connect the 4-pin header (VCC, GND, SCL, SDA) to your microcontroller's I2C bus. The sensor operates from 3.3V to 5V DC and refreshes up to 10 times per second. With its compact 16.5 x 11.5 mm footprint, it fits easily into embedded projects, thermal monitoring systems, or DIY weather stations.
