Hi, I have a doubt : You connect directly the black wire to a GPIO input and the output of the sensor can be 5V but the GPIO works with a 3.3V, Is it dangerous for the Raspberry pi? No contact with process media, Low-Cost The meter sends one pulse down to the remote unit for every 100 gallons of water used. At this point, the sensor and Home Assistant are paired. The sensor operates in cycles that can be defined. 3 jumper wires (female) to connect the NPN sensor to the GPIO on the Pi. Via the MobaXterm tool its easy drag & drop. Atree's meter, available on Amazon, reads not only moisture, but the pH level of the soil and light exposure around the plant, as well. I bought it in 6 dollars. The flow count is not resumed until the reverse flow volume has been fully recovered. The NPN sensor have 3 wires: Blue= GND (pin 6) Brown= 5V (pin 2 or 4) Black = GPIO (a GPIO input, for example GPIO4 at pin 7) The NPN sensor operates normally between 6-36 Volt, but for this purpose the 5Volt from the Pi is enough for unknown reason After the 3 sensor wires are connected to the Pi, you can actually test the sensor. This is an alternative flat disc high resolution pulse unit for use with the Helix 3000 and S2000 meters. Do more with your infrastructure. The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. I have one of these water meters (3/4" Water Meter with pulse output). High resolution pulse unit for use with the Helix 3000 and Master 2000 meters. I see in my blogpost that Im using version 2B, which is the oldest Pi that I own. Customer reviews of products and testimonials are also included. Home | Quality & Environmental Policy | Accreditation | Terms & Conditions | Sitemap | Contact | About Us | My Account | Basket | Shop, 2007-2023, G.J. Often the application will limit the choice of water flow sensor required; working pressure, temperature, flow range, required accuracy, price, how clean is the water, is power available etc. Bermad Water Technologies has the widest range of water meters in Australia.

Need Help Selecting a Pulse Output Water Meter? Is the script on the Pi triggered when there is a Pulse from the sensor? Robust . Its also important to make sure you buy a 5V version so you can power the sensor directly from the ESP. I have to admit that the same sensor and the same setup (identical watermeter, gasmeter has same distance to the watermeter as well as the other equipment, will give a lot of false measurements at the moment. You can buy this board at your favorite Chinese shop or Amazon somewhere for a price between 3-10 euros. I've chosen the 88pulses/L. If nothing happens, download GitHub Desktop and try again.

Low power consumption enables use with a battery powered emonTx or JeeNode. Flow sensors or flow indicators are flow meter devices used to measure the amount of liquid, gas or vapour that passes through them. Very strange this all. Also, there are many solutions written that need resistors to work. All MeiStream registers are prepared to receive the HRI-Mei.The HRI-Mei can also be mounted afterwards without breaking the meter's seal. Flow rates from 0.2 to 227 LPM / 0.06 to 60.0 GPM The switches attach with a single screw, and the are specially shaped so that it can only be installed the proper way, in exact alignment. data: I'm trying to get the ESP32 to run for a long time on a couple of cells to take regular measurements (ADC and/or count pulses), log them and then send the data daily. Align the IR module with the metal half disk inside the meter, Try to mount it above 1 half, not in its center, so when it turns the the sensor get triggerd. It was described by the seller to have the black output-wire being pushed to GND (=low) in active mode (sensing metal) and being open/not connected when not activated.
