Just write a simple YAML configuration file and get your own customized firmware Using the powders with pH 4.01 and pH 6.86 we obtain the voltages on the pin Po 3.04V and 2.54V respectively. The sensor is linear so by taking two points we can deduce the equation to convert the measured voltage to pH. The general formula would be y = mx + b, so we have to calculate m and b since x would be the voltage and y the pH. The result is y = -5.70x + 21.34 I am using pH sensor RC-A-41520 by Robocraze with ESP32 to monitor the pH of solutions. It is required to tune the adjustment screw such that it gives output 2.5V when the terminals of BNC connector are shorted (Input Voltage:5 V). I have tried the same but upon screw adjustment, I am not able to bring down voltage below 3.7 V. Therefore, I am not able to make use of full range of this sensor.

PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained - only needs power, ground and a resistor to set the delay time - and breadboard or perfboard. Here is an example of how I post humidity and temperature values that I collect from a DHT11 sensor. I use an ESP32 (Lolin32) board and I post values to a MQTT open source message broker (Eclipse Mosquitto) that I run alongside openhab on a Rpi3. Finally, I deep sleep the board to save energy.

I assume at least you're using some pH board that produces an analog output, so it's got to connect to the analog input of the NodeMCU. The typical(!) range of the NodeMCU analog input is 0-3.3V, but the range of the ESP8266's ADC is 0-1V (where the 1V, which is probably some kind of band gap, no doubt has some tolerance but I've never been able to find actual specifications of that tolerance)
pH (Power of Hydrogen) is the (-) negative log of hydrogen ion concentration in a water based solution described by Danish Biochemist Soren Peter Laurits Sorensen late 1909. pH has it value of 0 (ACID) and 14 (BASIC) in a neutral value of 7 see below the diagram for common substances of pH values . pH measurements are important in the field of agronomy, medicine, biology, chemistry.

Most low cost soil sensors are resistive style, where there's two prongs and the sensor measures the conductivity between the two. These work OK at first, but eventually start to oxidize because of the exposed metal. Even if they're gold plated! The resistivity measurement goes up and up, so you constantly have to re-calibrate your code. Also, resistive measurements don't always work in loose.

The Analog pH Sensor Kit is specially designed for Arduino controllers and has a built-in simple, convenient, and practical connection and features. It has an LED that works as the Power Indicator, a BNC connector, and a PH2.0 sensor interface. To use it, just connect the pH sensor with the BND connector, and plug the PH2.0 interface into the analog input port of any Arduino controller. If pre. This sensor comes in 2 parts, sensor probes and module board. The sensor is basically two probes to be inserted into soil. This sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily (less resistance), while dry soil conducts electricity poorly (more resistance) ESP32 DS18B20 Tutorial | DS18B20 Temperature Sensor ESP32 DHT11 Tutorial | DHT11 Humidity Temperature What is a Sensor?

I have to ensure that the 1v value corresponds to 0 degrees and the ph value of b 0 corresponds to 14 degrees ph. esp easy use with an esp-12e. thank yo
