A water level indicator is a device designed to measure and display the water level within a container, tank, or reservoir. It uses sensors or probes that are placed at different levels to detect the height of the water’s surface. These sensors then send signals to a control unit, which ...

By building a wireless water tank level indicator cum alarm, you can overcome numerous issues associated with wired alarms: It’s easier to install as you don’t need to pass any wires through or along the walls or ceilings. You can build one transmitter, mount it on the tank, and then ...
Blinker library for embedded hardware. Works with Arduino, ESP8266, ESP32. move to https://github.com/blinker-iot/blinker-library - i3water/blinker-library
In this case, a large increase in the pH sensor reading was observed, which, puts this indicator out of range, giving the water an alkaline behavior (Fig. 13). Moreover, a large increase in the ORP sensor reading was observed, yet keeping the ORP value within specifications. Vol:.(...
The latest solution comes courtesy of[Keilin Bickar], who’s using the ESP8266 and a serial TTL camera module to read the characters from the LCDof his water meter. With a 3D printed enclosure that doubles as a light source for the camera, the finished device perches on top of the wat...
Their system utilized electronic sensors to measure nine water quality parameters namely pH, temperature, turbidity, dissolved oxygen, electrical conductivity, total dissolved solids, carbon dioxide, ammonia, and water level. They used an Arduino Microcontroller to receive data from the sensors and ESP...
Therefore, the number of peaks in Vout over 15 s is a good indicator of MV (IMV); see Equation (5). When the MV increases the number of peaks will increase. I MV = n◦ o f peaks time (s) (5) Therefore, the number of peaks in Vout over 15 s is a good indicator of MV ...
Some researchers reported where ICT is utilised, but the system cost is very high due to using the commercially available sensor. Moreover, real-time water quality monitoring still relies on very few factors, including water temperature, velocity, level, conductivity, dissolved oxygen (DO), and ...
Using the received signal strength Indicator (RSSI), the maximum distance that a node can send data was 910 m while working at 968 MHz. Qian et al. [169] presented the design of a flexible RFID tag for sensing minerals in water using a smartphone. The front-end sensing module was a ...
