Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
SMS Based Water Supply Alert System
In this post I will show how to construct a circuit which will notify the user via SMS if the water supply to you area / home is initiated. It can show the time when the water is begin to supply and ended, average water flow speed in liter per minute and total water delivered […]
SMS Based Pump Controller with Automatic Dry Run Shut Off
In this post I will show how 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 […]
SMS Based Laser Security Circuit
In this post, I will show how to construct a laser security circuit which can send SMS alert to owner of the property or anyone else and activate loud alarm to deter the crook, which can be interfaced via relay. We always fear about crooks especially when we leave our property alone, this where security […]
LPG Leakage SMS Alert using MQ-135 – Get Warning Message in your Cellphone
In this article I will show how to construct an GSM based LPG leakage SMS alert circuit using Arduino, which alerts the recipient via SMS and surrounding people via beep, when LPG gas leaks out from the LPG cylinder or if there’s leakage due to improperly closed valve. Using MQ-135 as the Sensor We are […]
