172 Daniels Island Road, Mashpee, MA Ockway Bay tide measured using Maxbotix ultrasonic range sensor, Arduino and Sparkfun cellular shield. Updated hardware now uses a Particle Electron.

To calculate the distance via ultrasonic

This is data showing water level and volume for a reservoir. Reservoir devices are off the grid (no power, wifi) and use ESP32 (NodeMCU-32S)/Moteino Mega with JSN-SR04T sensors and Lora (Reyax RYLC896) to send results. Solar + 18650 LiPo bat for power

Channel that contains all the data gathered by FRED.

in this IOT project, Ultrasonic sensor is used to detect the fuel level in bike petrol tank and also using ESP8266 to upload that data in thinkspeak.
