SeeedGrove - Infrared Temperature Sensor (MLX90614)
Overview
The Seeed 101020894 is a Grove-compatible evaluation board featuring the Melexis MLX90614, a high-accuracy non-contact infrared thermometer. It integrates a 17-bit ADC and a powerful DSP to provide high-resolution temperature measurements ranging from -70 to +380 degrees Celsius for objects. The board uses the Grove interface for simplified 4-pin connectivity to microcontrollers using the SMBus protocol.
Why Choose This Part
This module provides exceptional precision with a 0.5 percent accuracy rating and a high 17-bit resolution. It includes a built-in oscillator and a low-noise amplifier to ensure signal integrity without requiring external timing components. The inclusion of CRC (Cyclic Redundancy Check) ensures reliable data transmission over the SMBus interface.
Applications
Key Specifications
Getting Started
Connect the module to a Grove Base Shield on an Arduino or Raspberry Pi and use the standard MLX90614 library to communicate via I2C/SMBus. Ensure the power supply is within the 4.5V to 5.5V range for optimal performance. You can read either the ambient temperature or the object temperature directly from the internal RAM registers.
