12V DC 1/2 inch Electric Solenoid Water Air Valve Switch (Normally Closed)
₹320.00Add to cart12V DC Solenoid Water Air Valve Switch?(Normally Closed)?1/2 controls the flow of fluid (liquid or air) and acts as a valve between high-pressure fluid! This liquid valve would make a great addition to your robotic gardening project.?There are two (Nominal NPT) outlets.?Normally, the valve is closed. When a 12V DC supply is applied to the two terminals, the valve opens and water can push through.
The valve works with the solenoid coil which operates electronically with DC 12 volt supply. As it is a normally closed assembly,?it opens the flow of fluids as soon as it is powered ON and stops/blocks the flow when the supply voltage removed.
MQ2 Flammable Gas and Smoke Sensor Module
₹120.00Add to cartThis is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. This module uses MQ2 Smoke & Flammable gas sensor as a gas sensing element. It requires no external components just plug in Vcc & ground pins and you are ready to go.
For Digital output the threshold value can be easily set by an on-board potentiometer.? Using this module you can easily interface MQ2 Smoke & Combustible gas Sensor to any Microcontroller, Arduino or even Raspberry Pi.
YF-S401 Water Flow Sensor
₹240.00Add to cartWith this sensor you can easily measure the flow of liquids (water).
The sensor has a 7mm coupling on both sides and is therefore easy to connect to?a 6mm hose.
The output of the sensor gives 98 pulses?per second with a duty cycle of approximately 50% for each liter of fluid passing through per minute: Q [L/min] = fpulse?[Hz]/98.
