# EnergyMonitor Arduino energy monitor, using SCT-013-030 current sensors Project Links : * [Software part, on GitHub](https://github.com/BmdOnline/EnergyMonitor) * [Hardware part, on Thingiverse](https://www.thingiverse.com/thing:3670139) This is a full energy monitor project : * You can manage 1 to 6 sensors. * You can configure it through USB (see below). * It can communicate through USB, with any homemade software. * It can communicate with any Home Automation System supporting MySensors (I'm using Domoticz). * Full source is provided, you can customize it. Needed parts : * For each sensor : * 1x SCT-013-030 current sensor ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=SCT+013+030)). * It also works with SCT-013-000 ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=SCT+013+000)) (see below). * 1x 3.5mm Audio jack socket ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=3.5mm+Audio+jack+socket)). * 2x 100k Resistor ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=100k+Resistor)). * 1x 10µF Capacitor ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=10uF+Capacitor)). * 1x NRF24L01 wireless module ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=NRF24L01)). * 1x 10µF Capacitor ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=10uF+Capacitor)) (see below). * 1x Arduino Nano ([AliExpress](https://www.aliexpress.com/wholesale?SearchText=Arduino+Nano)). Instructions : * Before to print case, you can specify how many sensors you have. * You can define the exact number of sensors, or plan more. Each socket will be pre-cut for future use. * Follow joined scheme for assembly. * Each sensor have to be connected to A0, A1 and so on... * Upload sketch to the Arduino Nano. * Connect it to any computer for configuration (see below). * Let's play... Configuration parameters : * Number of sensors, * Sensor calibration (Vrms, ICal, IOffset), * Sample frequency, * Transmission frequency, * Toggle MySensors on/off, * Toggle serial output on/off. Configuration will be saved to eeprom. Using serial console, you can communicate with the sensor. For example, using minicom (? for show help) : <pre><code>$ minicom -b 115200 -D /dev/ttyUSB0 __ __ ____ | \/ |_ _/ ___| ___ _ __ ___ ___ _ __ ___ | |\/| | | | \___ \ / _ \ `_ \/ __|/ _ \| `__/ __| | | | | |_| |___| | __/ | | \__ \ _ | | \__ \ |_| |_|\__, |____/ \___|_| |_|___/\___/|_| |___/ |___/ 2.3.1 Energy Sensor has powered up Energy Sensor (can use up to 6 sensors) F0:<val> : Sample frequency in seconds (F0:5) F1:<val> : Send frequency in seconds (F0:60) E#:[0|1] : Enable Sensor # (E0:1[;E1:1]) V<#:val> : Set Vrms (V0:230[;V1:230]) C<#:val> : Set ICal (I0:29.95[;I1:29.98]) O<#:val> : Set intensity offset (O0:0.05[;I1:0.07]) S[0|1] : Toggle Serial output T[0|1] : Enable MySensors transmission M<#> : Sensor mode (1: power, 2: current, 3: power+current) all commands are case insentitive F0:2;F1:60 E0:1:V0:230:C0:29.40:O0:0.01 E1:1:V1:230:C1:32.00:O1:0.05 S0;T1 M3 </code></pre> Latest lines show current configuration. Warning : If you are using SCT-013-000 instead of SCT-013-030, you have to add burden resistor. NRF24L01 may have connection issues. You have to add 10µF capacitor between PWR and GND. You'll be handling dangerous voltages. I decline any responsibility in case of any incident or accident.
