GPIO32-GPIO39: These pins can be used with the Analog To Digital Sensor to measure voltages. GPIO2: This pin is connected to the blue LED on the board. It also supports the touch pad binary sensor like some other pins.

The integrated operational amplifiers are available for the signal conditioning of the analog Hall-effect sensors and the shunt resistor signal. A comparator with a programmable threshold is integrated to perform the overcurrent protection .
We will connect the sensor as follows − Connect the +V s to +5v on your Arduino board. Connect V out to Analog0 or A0 on Arduino board. Connect GND with GND on Arduino. The Analog to Digital Converter (ADC) converts analog values into a digital approximation based on the formula ADC Value = sample * 1024 / reference voltage (+5v).
HY-40R201 Bluetooth low energy single mode module targeted for low power sensors and accessories. HY-40R201 offers all Bluetooth low energy features: radio, stack, profiles and application space for customer applications. The module also provides flexible hardware interfaces to connect sensors. HY-40R201 transmission distance of 100 meter or more.
I originally connected these sensors to the analog-to-digital (ADC) on an ESP32 microcontroller, testing it in both the Arduino IDE and ESPHome. The voltage was all over the place and produced garage readings. I ended up using instead an ADS1115 (16-Bit, 4 channel ADC) and connected it to the ESP32 via the I2C interface.

  • Perform some action (read from a sensor) Sleep for n microseconds; Repeat; It's important to note that the sleep time is specified in microseconds (µs). Fun fact, you can't sleep forever. According to the ESP8266 SDK, you can only sleep for 4,294,967,295 µs, which is about ~71 minutes. Now, let's dive into some code.

An RGB LED is a combination of 3 LEDs RED, Green and Blue. These three colors Red, green and blue can make any color. By varying supplied voltage to RGB LEDs different colors are formed. In the Node MCU different voltage are supplied using analog output function. An RGB LED has 4 pin interfaces. 3 Pins are for Red, Blue and Green.

The DHT11 temperature and humidity sensor is a nice little sensor that provides digital temperature and humidity readings. It’s really easy to set up, and only requires one wire for the data signal. These sensors are popular for use in remote weather stations, soil monitors, and home automation systems.

Mar 04, 2016 · A “stamp” of 16mm x 24mm device that connects to your WI-FI and with which you can make an infinite number of functions if you program it correctly. It represents to a certain extent the basis of the internet of things (and therefore also of the home automation). What does it do?
