DC power and energy meter with protection
For solar panels, batteries and DC supplies. It shows volts, amps, watts and watt-hours on a 16x2 LCD and logs CSV over USB. It also switches the load off on over-voltage, over-current, a short circuit or a flat battery.
Smart street light
A street light that's off in the day and dims itself at night. It only goes to full brightness when the PIR sensor sees someone on the road. On a quiet lane most of the night is spent at 20 to 40 %, so it uses much less energy than a lamp left at 100 %, and the LEDs last longer too.
Water tank level controller
Most houses in Nepal have the same setup: an underground sump (or a boring) and a tank on the roof. Someone has to remember to switch the pump on, and then remember to switch it off. This controller does both. More importantly, it protects the pump, because a motor running dry or against a closed…
Gas / smoke detector with SMS alert (v2)
An Arduino Uno watching an MQ-2 (LPG and smoke) and an MQ-3 (alcohol and vapour). On a confirmed leak it sounds the buzzer, starts the exhaust fan, closes the gas valve with a servo, and sends an SMS through a SIM900 module.
LED matrix scrolling display (scoreboard)
An Arduino Uno driving a chain of MAX7219 8×8 LED matrix modules with the MD_Parola library. Text scrolls across the display, and you can type a new message in the serial terminal.
