Waveshare Contact-less Infrared Temperature Sensor
The MLX90614 is an Infra-Red thermometer for non-contact temperature measurements. Both the IR-sensitive thermopile detector chip and the signal conditioning ASSP are integrated into the same TO-39 can.
Thanks to its low noise amplifier, 17-bit ADC, and powerful DSP unit, high accuracy, and resolution of the thermometer is achieved.
The thermometer comes factory calibrated with a digital PWM and SMBus (System Management Bus) output. As a standard, the 10-bit PWM is configured to continuously transmit the measured temperature in the range of -20…120˚C, with an output resolution of 0.14˚C.
In the case of working with an MCU:
VCC ↔ 3.3V ~ 5V
GND ↔ GND
SDA ↔ MCU.I2C data line
SCL ↔ MCU.I2C clock line
Application:
- High-precision contact-less temperature measurement
- Industrial temperature control
- Household appliances temperature control

Waveshare Contact-less Infrared Temperature Sensor Overview
The Waveshare Contact-less Infrared Temperature Sensor (Model MLX90614) is a non-contact thermometer module designed for precise surface and ambient temperature measurements. It integrates a thermopile detector, signal conditioning ASSP, 17-bit ADC and DSP unit in a single TO-39 can, offering high accuracy and fast response for industrial, laboratory, and DIY applications.
Key Features of Waveshare Contact-less Infrared Temperature Sensor
- Wide object temperature range: -70°C to 380°C and ambient measurement from 40°C to 85°C
- High resolution of 0.02°C with precision ±0.5°C in 0–50°C range
- Integrated low-noise amplifier, 17-bit ADC and powerful DSP for stable readings
- Dual output interfaces: 10-bit PWM (–20…120°C, 0.14°C resolution) and SMBus digital communication
- Operates from 3.3V to 5V for compatibility with Arduino, Raspberry Pi and other microcontrollers
- 35° field of view (FOV) for targeted measurement on small or distant objects
- Genuine Waveshare sensor, fast shipping across India from Zbotic
Applications and Use Cases
- Non-contact surface temperature checks on motors, bearings and PCB components
- Home automation: HVAC feedback and room temperature monitoring without probes
- Food safety: measuring temperature of cooked items or refrigerated goods
- Medical screening: quick forehead measurements in clinics or entry points
- Laboratory research: tracking temperature changes in chemical reactions
- Industrial processes: continuous monitoring on assembly lines and equipment
How to Use Waveshare Contact-less Infrared Temperature Sensor
Supply the MLX90614 with 3.3V–5V, connect SDA/SCL pins to your microcontroller’s I²C interface (SMBus compatible), and read ambient and object temperature registers via your chosen library. Alternatively, use the PWM output pin to get a continuous analog pulse train corresponding to measured temperature (–20…120°C range). Ensure the sensor lens is unobstructed and allow a short warm-up for stable readings.

Frequently Asked Questions
What is the difference between object and ambient temperature readings?
The MLX90614 provides two registers: one for object temperature (–70°C to 380°C) and one for ambient or “area” temperature (40°C to 85°C). Object is measured by the thermopile, while ambient reads the sensor’s own housing temperature.
How do I choose between PWM and SMBus output?
Use PWM output for simple pulse-width based temperature reporting in the narrow –20…120°C range (0.14°C steps). For full-range high-resolution data (0.02°C) and two-temperature readings, interface via SMBus (I²C compatible).
Can I integrate this sensor with Arduino or Raspberry Pi?
Yes. The sensor runs on 3.3V–5V, making it compatible out of the box. Install an MLX90614 library, connect SDA/SCL to your I²C pins, and begin reading temperature values with a few lines of code.
