Dismantaling of old water level controller & replacement with new Micro controller IoT Based Water Level Control System consist of a microcontroller, pump, adaptor, sensor ultrasonic, and a relay module to control the pump or valve on the hardware side. microcontroller with ESP8266 based, microcontroller triggering relay switch open and close. With ultrasonic sensor to read the level of the water container, the level that read from ultrasonic transducer is to decide when the pump is working and not working. On the ultrasonic sensor there a two cable for trigger the ultrasonic sensor and receive the echo of ultrasonic sound. The microcontroller communicating via the internet to connect with Blynk server and Web server (Water Container Monitoring Information System) A complete Software system using Water Container Monitoring Information System incorporated with a Blynk IoT server. the microcontroller must be communicating on Blynk server and a PHP web-based Water Container Monitoring Information System via sending data level every 4 seconds to Water Container Monitoring Information System using protocol GET. Data that send via GET protocol is using the token of microcontroller, the water level of water container and valve or pump status. From microcontroller, Water Container Monitoring Information System check is there any token on the database? If token exists, so the data from microcontroller will be saved in the database, otherwise if the token from microcontroller is not exist so the data will not be collected in the database. In Water Container Monitoring Information System, data of water level and valve/pump status is saved with a timestamp, so every data has its timestamp. Micro controller also send data to Blynk server but data that send to Blynk server only save into file not into the database so that why we need a Water Container Monitoring Information System. Beside microcontroller send to data to Blynk server microcontroller also receive configuration data from Blynk server.

(Contd.......) The configuration data is water container height, Max upper-level limit, lower-level limit, mode and on/off the pump on configuration mode divided into two modes, which is auto and semi-auto. In auto mode, pump/valve automatically fill water container if the level is below the lower level limit and stop when the level of water is above or same as the upper-level limit. In semi-auto mode, if on/off in position on, the microcontroller works like auto mode, but if on/off in position off, the pump/valve will stay off until on/off in place on. A PHP Web-based Water Container Monitoring Information System is also communicating with Blynk server for change configuration using API (Application Programming Interface) so the user can change configuration data on Blynk server using Water Container Monitoring Information System also from Blynk Application on the smartphone. Ultra sensor must shoot ultrasonic pulse to the water surface and capture ultrasonic pulse reflection from the water surface. The different time between sensor ultrasonic shoot pulse and receive pulse must be converted into the distance (cm). After getting water level from the sensor, the next step by controller is to subtracting level from the sensor with a height of water container because if the water container is near full, the level from the sensor is shrinking, Push data to Water Container Monitoring Information System is run every 4 seconds so the server is not overloading. Push data to Blynk server run every 1 second. Minimum 1SO 9001:2015 Certified. Only Original OEM is entitled for work . Contractor has to ensure it.
