Details
contact-less infrared template sensor
Overview
- Measures the surface temperature of an object without touching it, depending on the emitted IR waves of the target
- Also measures the average temperature over an area
- Contact-less, high precision, high resolution, fast response
- Calibrated before delivery, with gradient temperature compensation
- Works with 3.3V/5V MCU system directly, thanks to the built-in level translation
Specifications
- Power: 3.3V ~ 5V
- Measuring range (area): 40°C ~ 85 °C
- Measuring range (object): -70°C ~ 380 °C
- Resolution: 0.02°C
- Precision: ±0.5°C ( 0~50°C)
- Field of view (FOV): 35°
- Dimension: 28mm x 16 mm
- Mounting holes size: 2.0mm
Applications
- High-precision contact-less temperature measurement
- Industrial temperature control
- Household appliances temperature control
How to Use
In the case of working with a MCU:
- VCC ↔ 3.3V ~ 5V
- GND ↔ GND
- SDA ↔ MCU.I2C data line
- SCL ↔ MCU.I2C clock line
