Đo nhiệt độ không tiếp xúc MLX90640 Waveshare

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
