Seamless Integration of ZigBee Wireless Ambient Detectors with ESP32-Based Systems Using ThingSpeak Application

The Internet of Things (IoT) has witnessed remarkable growth in recent years, with countless applications ranging from smart homes to industrial automation. To achieve effective IoT solutions, the integration of various sensor devices with connectivity platforms is crucial. This paper focuses on the integration of ZigBee wireless ambient detectors, which measure PM2.5, temperature, humidity, and illuminance, with ESP32-based systems using the ThingSpeak application. The sensors employed in this integration include the current transformer (CT) for electric current level detection, the PMS5003 for particulate matter measurement, the DHT22 for temperature and humidity sensing, and an LDR for illuminance measurement. This comprehensive approach leverages the capabilities of the ESP32-based system, including the MEGA Pro2560 microcontroller, to collect, process, and display sensor data via a 16x2 LCD screen in real-time. Additionally, the data is seamlessly transmitted to the ThingSpeak cloud platform for further analysis and remote monitoring.
