/* * The MySensors Arduino library handles the wireless radio link and protocol * between your home built sensors/actuators and HA controller of choice. * The sensors forms a self healing radio network with optional repeaters. Each * repeater and gateway builds a routing tables in EEPROM which keeps track of the * network topology allowing messages to be routed to nodes. * * Created by Henrik Ekblad * Copyright (C) 2013-2026 Sensnology AB * Full contributor list: https://github.com/mysensors/MySensors/graphs/contributors * * Documentation: http://www.mysensors.org * Support Forum: http://forum.mysensors.org * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * version 2 as published by the Free Software Foundation. * ******************************* * * REVISION HISTORY * Version 1.0 - Henrik EKblad * * DESCRIPTION * Example sketch showing how to measure light level using a LM393 photo-resistor * http://www.mysensors.org/build/light */ // Enable debug prints to serial monitor #define MY_DEBUG // Enable and select radio type attached #define MY_RADIO_RF24 //#define MY_RADIO_NRF5_ESB //#define MY_RADIO_RFM69 //#define MY_RADIO_RFM95 #include #define CHILD_ID_LIGHT 0 #define LIGHT_SENSOR_ANALOG_PIN 0 uint32_t SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds) MyMessage msg(CHILD_ID_LIGHT, V_LIGHT_LEVEL); int lastLightLevel; void presentation() { // Send the sketch version information to the gateway and Controller sendSketchInfo("Light Sensor", "1.0"); // Register all sensors to gateway (they will be created as child devices) present(CHILD_ID_LIGHT, S_LIGHT_LEVEL); } void loop() { int16_t lightLevel = (1023-analogRead(LIGHT_SENSOR_ANALOG_PIN))/10.23; Serial.println(lightLevel); if (lightLevel != lastLightLevel) { send(msg.set(lightLevel)); lastLightLevel = lightLevel; } sleep(SLEEP_TIME); }
