MLX90642 32×24 Thermal IR Array Sensor

The MLX90642 is a factory-calibrated 32×24 far-infrared thermal array sensor for compact thermal imaging and non-contact temperature sensing. It provides 768 FIR pixels, digital I2C output, programmable 2–16Hz refresh rate, and two FOV options: 110°×75° and 45°×35°. Suitable for thermal imagers, occupancy detection, intrusion sensing, HVAC monitoring, and industrial hotspot detection.

1. 32×24 FIR Thermal Array

Provides 768 far-infrared sensing pixels for low-resolution thermal imaging, temperature mapping, presence detection, and thermal monitoring.

2. Factory-Calibrated Temperature Output

The sensor is factory calibrated and provides access to object temperature data through a digital I2C-compatible interface, reducing integration complexity.

3. 0.065K NETD Thermal Sensitivity

Achieves 0.065K NETD at 2Hz, helping detect small temperature differences in thermal monitoring and hotspot detection applications.

4. Two FOV Options

Choose 110°×75° wide-angle for area coverage or 45°×35° narrow-angle for more focused temperature monitoring.

5. Compact TO39 Package

Uses an industry-standard 4-lead TO39 package, supports 3.0V–3.6V operation, and is pin-compatible with MLX90640 for easier hardware evaluation.
