Qijian smart version is a suite of functions such as water change, temperature detection, liquid level detection, humidity detection, pH detection, conductivity and salinity detection, 8-way smart socket, etc. Users can view the real-time value and the historical value of the sensor through iOS or Android App. User can control the switch of the smart socket, set the plan parameters of the water change. When the device is powered down or the sensor is abnormal, the alarm information can also be pushed to the mobile app.1. KICC controller2. S3 EC sensor module3. Sockets4. S3 basic sensor module5.

Power supply for modules KICC controller It is the brain that runs various functional modules of scheduling, including data storage, communication interface, network communication, and function scheduling. 2. S3 EC Sensor Module It contains 1 channel pH, 1 channel EC, 1 channel temperature sensor, which can detect the water quality. You can detect the real-time value of these sensors through the mobile app. When the value is abnormal, you can push the alarm information to the mobile phone. 3. Sockets 8 independent sockets controlled by P8 smart socket control module. 4. S3 basic sensor module It includes 5 level sensors, 2 temperature sensors, 1 temperature and humidity sensor. Through these sensors, it can monitor the liquid level of fish tank, hydration bucket and waste liquid tank, monitor the temperature and humidity of the environment, and fish tank. Temperature, etc., the real-time and historical values of these sensors can be viewed through the mobile app. 5. Main power switch After the device is connected to the power supply, the switch needs to be turned on, and each module can be powered on. 6. Power supply for P8 smart socket control module Powering the smart socket control module and the 8-way socket, turning on the switch, the smart socket control module is powered, if the smart socket is not used, the switch can be turned off separately. 7. P8 smart socket control module The socket switch can be controlled on time by the mobile phone App setting plan, and the socket and the sensor can be set to be linked, and the socket performs a certain action when the sensor reaches a certain value. 8. Power supply for modules It includes 2 5V DC power supplies and 2 12V DC power supplies.
