NODEMCUESP8266 Wi-Fi module is used as a primary microcontroller that is attached to the sensors, such as temperature and variety of fumes sensors, which can continuously monitor leakage. A warning alarm is generated immediately if any leakage is found in either pipeline of the system and the ...
The mains current measurement was done with the same iSnail current sensor that we used on the previous logger. This gives a 0-5V output so we used a voltage divider to half the voltage and then fed it into an ADS1115 16-bit ADC from Texas Instruments. The ADS1115 is an I2C-based d...
The battery supplies power to the charging module, which in turn provides power to the node-MCU ESP8266 via a switch key. The charging module also serves as a battery charger. The gas sensor is directly connected to the battery to minimize the pre-heating time. The output signal of the ...
This library has been tested with NodeMCU (ESP8266) Arduino Pro Mini Arduino Nanosee [WARNING] below ESP32 Note that the CCS811 requires a supply voltage of 1.8V .. 3.6V. So, 3.3V is ok, butdo not use a 5V board. The Nano has a "3v3 out" pin, but that's only a power out ...

This research focuses on design and implementation of a sensor-based system to sense the existence of garbage gases, namely Methane (CH4), Hydrogen Sulfide (H2S), and Ammonia (NH3). Our sensor device consists of an Arduino Uno, a NodeMCU ESP8266, MQ-136, MQ-137, and TGS-2611 sensors. ...
The calibration data obtained from the calibration method is input into computer programming and processed by the ESP8266 microprocessor. After calibration, the MQ-137 gas sensor and pH sensor modules are used to measure the ammonia gas concentration and pH levels in the Chlorella sp. ponds. ...
