External Analog Sensor Module
Connect analog temperature, light, pressure, humidity and soil sensors to NetRelay with the external module. Measurements are used for threshold triggers, irrigation/conditioning scenarios, and MQTT telemetry.
What measurements?
You can read environmental data such as temperature, light level, pressure, ambient humidity and soil moisture via high-gain analog inputs.
automation cycle
Relay on/off, email/SMS alert or MQTT publish when sensor threshold is exceeded. The same I/O model is used in agriculture, greenhouse, server room and site management.
