Definitely seeing the +/- 5% difference in output.A few things I discovered:* The sensor needs at least 8V. I had a 9v power supply left over from some other equipment. However, a raspberry PI can only take 3.3V into its GPIO port. (and no pull-up resistor is needed) So I sent 8V into this sensor, and on the output pin I installed a 10k resistor tied to ground. This dropped the output voltage to around 3.7V.* I wanted to record data in gallons per hour. This is from my most recent calibration where I dumped water into a bucket marked off with quarters of a gallon on the side.total_gal = total_gal + 0.001115 # 897 pulses per gal = 0.001115 gal per pulse. This code runs whenever a change from high to low occurs on the output pin.flow = (count / 897.0)*3600 # pulses/897 is gal per sec. *3600 is gal per hour* the label faces down. There is a lot of play in the spindle inside. making the label face down puts the impeller more directly in line with the water flow* make sure you install it in the right direction. The arrow on the label was correct for me.* I used waterproof automotive plugs, sealed on the ends with caulk, since this thing will be outside measuring the irrigation water usage. ### ⭐⭐⭐⭐⭐ Measure water flow well *by on Reviewed in the United States 31 July 2025* Works well with standard microcontrollers. 5VDC needed ## Frequently Bought Together - GREDIA 1" Water Flow Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter Counter 1-60L/min (Pack of 2） - Ximimark 2Pcs 1/2" Thread Plastic Electric Solenoid Valve Water Inlet Flow Switch Magnetic Water Air Normally Closed Tools DC 12V N/C 0.02 to 0.8mpa - GREDIA 3/4" DC 12V Solenoid Valve N/C Normally Closed Water Inlet Flow Switch --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/608612170-1-water-flow-sensor-food-grade-switch-hall-effect-flowmeter](https://www.desertcart.fr/products/608612170-1-water-flow-sensor-food-grade-switch-hall-effect-flowmeter) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-05-30*
