12.非接触式红外测温模块, Non-contact Temperature Sensor
code:112
Up for sale is a MELEXIS MLX90614ESF-BAA-000-TU-ND non-contact infrared thermometer for use with Arduino, or any microcontroller that can communicate with it through it's I2C interface. This sensor comes with a breakout board with all of the components needed for operation and two types of pins. They are unsoldered. Please indicate if you would like one or the other soldered. There are two solder jumpers for the I2C interface that may or may not need to be soldered depending on your application, but will not for most uses. From the manufacturer:
Features and Benefits: Small size, low cost Mounted on a breakout board with two types of pins 10k Pull up resistors for the I2C interface with optional solder jumpers Easy to integrate Factory calibrated in wide temperature range: -40…+125°C for sensor temperature and -70…+380°C for object temperature. High accuracy of 0.5°C over wide temperaturerange (0…+50°C for both Ta and To) High (medical) accuracy calibration Measurement resolution of 0.02°C Single and dual zone versions SMBus compatible digital interface Customizable PWM output for continuousreading Simple adaptation for 8…16V applications Sleep mode for reduced power consumption Different package options for applications andmeasurements versatility Automotive grade
Applications Examples: High precision non-contact temperaturemeasurements Thermal Comfort sensor for Mobile AirConditioning control system Temperature sensing element for residential,commercial and industrial building airconditioning Windshield defogging Automotive blind angle detection Industrial temperature control of moving parts Temperature control in printers and copiers Home appliances with temperature control Healthcare Livestock monitoring Movement detection Multiple zone temperature control – up to 127sensors can be read via common 2 wires Thermal relay / alert Body temperature measurement
这个库使用起来很简单，首先，模块上有四个引脚，VCC接5V，GND接地，SCL接Arduino Nano的A5, SDA接Arduino Nano的A4。
然后在Arduino IDE中，搜索库：MLX90614，安装 Adafruit_MLX90614 这个版本的就可以。然后就可以使用例程来测试了。非常简单。
