With COVID-19 still wreaking havoc globally, causing thousands of deaths, millions hospitalized, any useful medical device is on high demand, especially household medical device like IR non-contact thermometer. Handheld thermometer usually is on high price point and is hard to come by these days, but the components needed to make thermometer are not that expensive, that give us the perfect reason to DIY one during this lockdown period.
This ThermoGun project use Ameba Dev. board RTL8710AF from Realtek, which connects to an OLED display to show temperature data obtained from the MLX90615 IR sensor. Pushing the push button not only perform data acquisition and visualization, but also publish the data via MQTT to all subscribers.
Note: The MQTT service used in this project is a FREE MQTT broker hosted at cloud.amebaiot.com, which need to register at www.amebaiot.com . Details of registration is at the link below, Cloud: Getting Started – Realtek IoT/Wi-Fi MCU Solutions
