Description

This sensor module integrates the MLX90615 infrared thermopile detector and signal conditioning ASIC into a single package, providing a calibrated digital temperature reading via the SMBus (System Management Bus) protocol. The onboard 16-bit ADC and DSP unit enable precise temperature measurements with embedded emissivity compensation, making it suitable for applications requiring non-invasive thermal monitoring.

The module is designed for low-power embedded systems and supports daisy-chaining of up to 127 sensors on a common two-wire bus. Its compact form factor and Grove ecosystem compatibility simplify prototyping and integration into IoT devices, environmental monitoring stations, and industrial control systems.

Key Features

  • MLX90615-based non-contact infrared temperature sensor.
  • Digital SMBus output for reliable communication with microcontrollers.
  • High-value build with integrated low-noise amplifier and 16-bit ADC.
  • Wide ambient operating temperature range from -40°C to +85°C.
  • Power-saving mode for battery-operated applications.
  • Durable construction with a standard Grove JST connector.
  • Optimized performance-to-cost ratio for accurate thermal sensing.

Frequently Asked Questions

What is the operating voltage range for this Grove IR temperature sensor?

The module requires a supply voltage between 2.6V and 3.4V DC. It is designed for 3.3V logic systems and is not 5V tolerant. Exceeding 3.4V may damage the sensitive MLX90615 sensor IC.

How do I connect and communicate with this sensor using an Arduino?

Connect the module's Grove JST cable to an I2C Grove port or directly wire the SDA and SCL pins to your microcontroller's I2C bus. The sensor uses the SMBus protocol, which is compatible with standard I2C libraries. Ensure you use a 3.3V logic level and include appropriate pull-up resistors on the bus.

What is the difference between the object temperature and ambient temperature ranges?

The object temperature range (-40°C to +115°C) refers to the surface temperature of the target being measured non-contact. The ambient temperature range (-40°C to +85°C) is the operating environment temperature for the sensor module itself. The sensor compensates for its own temperature to provide an accurate object reading.

Can multiple sensors be connected on the same bus?

Yes, the SMBus interface supports up to 127 devices on a common two-wire bus. Each MLX90615 has a programmable address, allowing for multi-point temperature monitoring in systems like thermal arrays or distributed environmental sensors.
