You'd be far better off waiting until you have data to report before you bring up the network. Hi, i have uploaded the sketch and done the SSID/Password changes. In my case, I have selected the Gauge Widget. Untuk mengirimkan data penggunaan air dari sensor ke cloud maka dibutuhkan internet. To review, open the file in an editor that reveals hidden Unicode characters. Bypass regulators and use raw LiFePO4 voltage. flowRate = 0.0; Post How would this work though as when I look into the water flow meters pulses it seems it sends a value (even if 0) every second or so, this would the reset the chip every time, no? Lets get to the programming section now. So sign in to yourThinger.ioaccount and follow the below steps to connect your device. thing.handle(); Admittedly my setup is now a bit more complex as I have an extra always-on ESP8266 acting as the ESP-Now hub but using the same LiFePo4 cell my sensor has lasted 12 weeks so far and still going strong with only a small dip in the reported cell voltage. How can I resolve this error?? Therefore, we will create a straightforward IoT-based water flow meter using the YFS201 Hall Effect Water Flow Sensor and ESP8266.

Before I added a solar panel to top it up it managed 16 hours at 5 min sleep intervals so it seems likely your flow meter is a power hog and or the battery shield is.I stopped tinkering with power saving once I added the solar charging as even on the worst winter day there's some input, I've only externally charged the battery once in 3 years.For the ultimate in low power ESPs check out the TinyPICO board, not exactly cheap but not unreasonable for what it's capable of. The MQTT Protocol can also be used to improve wireless communication. In the next step, we will program the NodeMCU to send the data to the Thinger.io platform. by grovkillen 21 May 2019, 10:46, #3 The Red wire is used for supply voltage ranging from 5V to 18V, and the Black wire is GND. The whole "sleep based on time of day" seems like nonsense. Open the app and set up a New Project. Step 3: Select Write API Key after clicking on API Key. I'm trying to build a water counter on my house using a node mcu esp8266 and a SEN-HZ43WB g3-4 here's the link for the water flow i have: One other thing i have done on the formula was this: %value%*60/477 i did get some values but i dont believe they are rigth. On the esp easy log e get values like this: You zero the counter at the end of the set interval. The Gerber file for all the PCBs is given below. attachInterrupt(digitalPinToInterrupt(SENSOR), pulseCounter, FALLING); By counting the pulses coming from the sensors output, the water flow rate may be determined. Press question mark to learn the rest of the keyboard shortcuts, https://www.youtube.com/watch?v=rfPwOtoGO4E. Also on to which cloud http is the data sending, where do I specify the same? Saya masih belum mengerti, saya mencoba menampilkan pulseCount++ itu keluar 67 per/s. That's 159 per 10 seconds (which is the interval you have). 
About 2.25 milliliters make up each pulse. I then swapped to the ESP-Now protocol and the ESP is awake for a fraction of a second, too quick for my multimeter to take current reading before returning to deepsleep. pulseCount++; HOME WATER MONITORING USING WATER FLOW SENSOR AND NODEMCU, ESP8266 only works when I disconnect from the IDE. I also understand your point on using the pulse as wake-up with the transistor changing the signal (?). All Rights Reserved. Andreas Spiess on YouTube has several videos about running ESP8266 and other microcontrollers on batteries.

terimaksih. Hence my post here if someone could give me additional advice on code (I only started out programming, as for sure you can see at my code) or overall setup, or tell me that within a 3min wake-up it is even not possible to get more battery time. But now let us see the IoT Water Flow Meter Circuit Diagram & Connection. GlI&Q7MT(bjj In the attachInterrupt() function, it is specified that SENSOR is the external interrupt pin, and pulseCounter function is called whenever a pulse is received. Serial.print(totalMilliLitres); WiFi login and MQTT (if no water is running obviously), is there anything in the code that would use too much power? Post This would mean connecting the battery directly to 3.3 and GND correct? #define SSID_PASSWORD "Password" Serial.print(int(flowRate)); // Print the integer part of the variable Data Bucks, Dashboard, and Endpoint, to work with devices data; these tools can be used to visualize the device data, extend the interoperability of the devices. About ScienceDirectShopping cartContact and supportTerms and conditionsPrivacy policy. The Thingspeak Setup Part has concluded. Post It will calculate the flow rate and quantity of water and send it to the cloud (Thinger.IO) to monitor the consumption of water. Serial.print("L/min"); Step 1:The first step is to create a new device. The water flow sensor works on the principle of the Hall Effect. My maximum is 25L/min. You can download the Gerber file and order the PCB online from NextPCB.
