Anti-Corrosion Probes for Water Level Controller Circuits

In this post we learn how to make anti-corrosion probes for water level sensor and controller circuits by using alternating supply across the probes. Let’s understand the concept used behind the designing of this anti-corrosion probe circuit for water level sensors and controllers. Corrosion in water level sensor probes take place due to DC supply … Read more

GSM Pump Motor Controller Circuit using Arduino Part-1

In this post we are going to construct a farmer friendly GSM pump motor controller circuit which could turn on and off the irrigation system remotely from anywhere in the world via cellphone SMS and return you with an acknowledgement message. The idea was requested by Mr. PG Ragavandir. By: Girish Radhakrishnan   The Request … Read more
