BuildingPulse LCT1 is a low-power LoraWAN AC current and temperature sensor. It can be used to measure the AC electrical current (apparent, real, reactive, and power factor), and the temperature of air, liquid or object, and and then upload to IoT server via LoRaWAN wireless protocol.
For example, monitor the temperature and electrical current use of your air conditioning or chiller, or measure the temperature and current of a motor under load.
The current sensor is an AccuCT 50A x 10mm split-core 50mA current transformer for measuring 50/60 HZ AC electrical current. One or three phase measurements are supported.
Voltage phase is sensed using a non-contact probe. No direct voltage connection is needed. Also, the LCT1 is self powered with battery backup. The internal battery is recharged via the CT when the primary current is greater than 10% of CT rated current. This makes for a quick and easy install!
The temperature sensor is DS18B20, which can measure -55°C ~ 125°C with accuracy ±0.5°C (max ±2.0 °C). There are three sensor cables which are waterproof, moisture-proof and anti-rust for long term usage.
At the end of your use, please send the components back to us and we will pay you $20 assuming some of the components are still serviceable.
Device main features
For a single phase load, with two wires, you need one CT. For a load with three wires (no neutral) you would put CTs on three of the wires. For four wires (with neutral) you would put CTs on three of the wires.
Air conditioners and chillers use lots of electrical power and this is a way to monitor them simply and affordably.
We made this device for our own needs... Does anyone want it? Its very ugly at the moment but we would like to start offering it to others.
The BuildingPulse LCT1 is designed to monitor HVACR air conditioners, heat pumps, and chillers, or any AC electrical load. Electrical current and temperature are able to be monitored using a LoraWAN network. The device may be modified by editing the Micropython source code. You may monitor the measurements using node-red, influxdb, and grafana, or use our buildingPULSE app for a small ongoing cost.
CT energy harvesting means the product needs no external power source and will continue to operate for a long time in many use cases.
