Ultrasonic Wireless Water Level Indicator – Solar Powered

In this post we are going to construct a ultrasonic based solar powered wireless water level indicator using Arduino in which the Arduinos would be transmitting and receiving at 2.4 GHz wireless frequency. We will be detecting the water level in the tank using ultasonics instead of traditional electrode method. Overview Water level indicator is … Read moreUltrasonic Wireless Water Level Indicator – Solar Powered

SMS Based Pump Controller with Automatic Dry Run Shut Off

In this post we are going to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected.  We will also construct another much simpler automatic dry run preventer circuit without GSM in the next half of the article. What is Dry Run in Motors … Read moreSMS Based Pump Controller with Automatic Dry Run Shut Off

Car Tank Water Sensor Circuit

The article explains a simple car tank water sensor alarm circuit using IC 555 and a pulsating signal on the sensing probes to pevent corrosion on the probes. The idea was requested by Mr. Peter. Circuit Objectives and Requirements I couldn’t find how to post a project proposal on your website. May be you can … Read moreCar Tank Water Sensor Circuit
