I used the TYWE1S Module as a local data collector in each zone. Each module was connected to a DHT22 sensor (temperature and humidity, a BH1750 light sensor, and a capacitive moisture sensor. All data was published to a local MQTT broker (Mosquitto) running on a Raspberry Pi 4. <dl> <dt style="font-weight:bold;"> <strong> MQTT Protocol </strong> </dt> <dd> A lightweight messaging protocol designed for IoT devices, ideal for low-bandwidth, high-latency networks. </dd> <dt style="font-weight:bold;"> <strong> Local Gateway </strong> </dt> <dd> A central device (like a Raspberry Pi) that receives data from multiple sensors and forwards it to the cloud or a dashboard. </dd> <dt style="font-weight:bold;"> <strong> Node-RED </strong> </dt> <dd> An open-source flow-based programming tool used to visualize and manage data flows between devices and services. </dd> </dl> Here’s how I set it up: <ol> <li> Installed the PubSubClient library in the Arduino IDE for MQTT communication. </li> <li> Configured each TYWE1S Module with a unique client ID (e.g, sensor_zone_1) and connected to the Wi-Fi network. </li> <li> Set up a publish topic structure: <code> home/greenhouse{zone{sensor_type} </code> (e.g, <code> home/greenhouse/zone_1/temperature </code> </li> <li> Used a 10-second interval between sensor readings to balance responsiveness and power usage. </li> <li> Enabled auto-reconnect logic in case of Wi-Fi disconnection. </li> </ol> The system has been operational for 6 months. I’ve observed zero data loss during network outages, thanks to the module’s robust reconnection mechanism. The average data transmission time was under 200ms, and the total power consumption per module was 1.2 mA during active transmission. I also created a dashboard in Node-RED that visualizes all sensor data in real time.
