Description
The GY-906-BCC is an industrial-grade infrared thermometer designed for high-accuracy temperature sensing without physical contact. By measuring the infrared light radiating from an object, it can calculate the surface temperature with incredible precision.
Key Advantages of the BCC Version:
- Narrow 35° Field of View: The standard version (BAA) has a 90° wide angle, meaning it averages everything in a large area. The BCC version focuses on a smaller spot, making it ideal for medical thermometers or measuring specific components in a tight space.
- Medical Accuracy: Factory calibrated to provide high precision (±0.5°C) within the human body temperature range.
-
Advanced Noise Reduction: Features an internal 17-bit ADC and powerful Digital Signal Processing (DSP) for stable readings.
- Multi-Interface: Supports both SMBus (I2C) for digital data and a PWM output for continuous reading.
