Product Description

Experience medical-grade precision with the MLX90614-DCI Infrared Temperature Measurement Module. Unlike standard contact thermistors, this sensor measures thermal radiation to calculate temperature without touching the subject. At Robogears, we recommend the DCI version specifically for its narrow Field of View (FOV), which allows for more accurate distance-based readings. The module is factory-calibrated and features an internal 17-bit ADC and powerful DSP (Digital Signal Processing) unit, ensuring high-resolution data output. Whether you are building an automated thermal scanner for your Pimpri facility or a contactless industrial thermometer, the MLX90614 provides industry-standard reliability and accuracy.

Detailed Key Features

  • Non-Contact Measurement: Eliminates the risk of cross-contamination and allows for temperature reading of moving or hard-to-reach objects.

  • Medical Grade Accuracy: Specifically tuned for human body temperature measurement with a precision of 0.5°C, making it suitable for health-screening kiosks.

  • Narrow Field of View (DCI): The DCI variant features an integrated gradient compensation and a narrower sensing cone, providing better focus on the target at a distance of 5-10cm.

  • Dual-Zone Detection: Capable of reading both the ambient temperature and the object temperature simultaneously.

  • I2C Serial Interface: Uses the SMBus standard, allowing multiple sensors to be connected to the same bus using just two wires.

All Technical Details

  • Pinout:

    • VCC/GND: Power Input.

    • SCL/SDA: I2C Clock and Data lines.

  • PWM Output: Can be configured to output a PWM signal for simpler integration without an I2C stack.

  • Thermal Gradient Compensation: Internal logic compensates for rapid changes in the sensor's own temperature, maintaining accuracy in fluctuating environments.

  • Applications: Fever detection systems, industrial melt-temperature monitoring, automotive climate control, and smart home appliances.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Distance is Key: At our Pimpri workshop, we’ve found that the most accurate readings for human skin are taken at a distance of 2cm to 5cm. While the DCI version can sense from further away, the "spot size" grows with distance, potentially averaging the background temperature into your reading.

  • The "Emissivity" Factor: Most organic materials (and human skin) have an emissivity of ~0.95. If you are measuring polished metals, you may need to adjust the emissivity constant in your code to avoid inaccurate low readings.

  • Thermal Equilibrium: If you move the sensor from a cold office to a hot warehouse, allow the module 10–15 minutes to reach thermal equilibrium with the environment before trusting its readings.

  • I2C Pull-ups: This module usually comes with on-board pull-up resistors. If you are using long wires or multiple I2C devices, ensure your pull-up resistance is around 4.7kΩ to maintain signal integrity at high speeds.

Package Includes

  • 1 x MLX90614-DCI Non-Contact Infrared Temperature Module
