Using A Flow Sensor With Arduino BC Robotics

In this tutorial we will be hooking up a Flow Sensor to an Arduino Uno to measure liquid flow. This type of flow sensor is designed to measure the volume of liquid traveling past a given point, a great way to keep tabs on how much water your drip irrigation system is using, or any other project were the flow of liquid needs to be tracked.

Reading a TUF2000M Ultrasonic Flow Meter with an Arduino ...

· It’s not quite as clear of a signal as a flood sensor, but if I detect flow when everyone is asleep or when on vacation, I can be sure that something is going wrong and have Home Assistant give me an alert. I didn’t want to cut into my water main and put a inline flow meter in, so when I saw a reasonably priced clampon ultrasonic flow meter called the TUF2000M, I had to bite. The TUF ...

How to Interface an Arduino With a Flow Rate Sensor to ...

· In this Arduino flow rate sensor, for every liter of liquid passing through it per minute, it outputs about pulses. Dividing the total pulse count by will give you the total amount of liquid passing through it in liters per minute. Multiplying that by 60 will give you the flow rate in liters per hour, which gives us the total amount or ...

· system January 8, 2009, 12:20am 2. There was a suggestion in Elektor magazine a few months ago, using a small incandescent light bulb as a sensor. You have to break off the glass bulb without breaking the filament, then run a constant current through the filament. Gas flow over the bare filament will then cool it, changing its resistance.

Carbon Monoxide Gas Sensor MQ7 Arduino Project Hub

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem.
