DHT22( AM2302) : Pin Diagram, Circuit, Specifications
It is available as a sensor as well as Module. Block Diagram. The DHT22 sensor is the successor of the DHT11 sensor. DHT22 is available as a sensor as well as a module. The functioning of both sensor and module of DHT22 are similar. The difference lies in the internal circuitry. The module contains an in-built filtering capacitor and pull-up
5V Relay Module : Pin Configuration, Circuit, Working
The circuit diagram of the single-channel relay module circuit is shown below. In this circuit, we can observe that how the relay module is activated and deactivated through a digital signal. This signal is applied to a control pin of the relay module. The following circuit diagram is the internal 5V single channel relay module diagram. Single
RF module - Wikipedia
An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices an embedded system it is often desirable to communicate with another device wirelessly wireless communication may be accomplished through optical communication or through radio-frequency (RF) communication.
How to use the DHT11 with Arduino - Code, Circuit Diagram
Feb 27, 2020In these tutorials, we will measure Temperature and Humidity by using DHT11 with Arduino. Here we also display those readings on an LCD Display. The DHT11 Temperature and Humidity Sensor senses, measures and regularly reports the relative humidity in the air. It measures both moisture and air temperature.

Rain Drop Sensor Module Pinout, Working, Interfacing with
Circuit Diagram. The functional diagram of the Rain Drop Sensor module for conceiving the knowledge of the internal connections of the module is provided below: Interfacing with Arduino. Zigbee Interfacing. RF Transmitter and Receiver. Arduino Projects. ATS Circuit.
Getting Started with HC-05 Bluetooth Module & Arduino
Apr 12, 2019But we strongly recommend 3 voltage, since the logic of HC05 serial communication pins is 3. Supplying 5V to the module can cause damage to the module. In order to prevent the module from damages and make it work properly, you should use a resistance division circuit (5v to 3 ) between arduino TX pin and module RX pin.
HM-10 Bluetooth Module Pinout, Applications, Interfacing

The ground pin is always important for every DC circuit to make the common ground with power and other devices for proper function. GND pin will help to fulfill the requirement. Zigbee Interfacing.
LoRa Communication between two Arduino using LoRa Module
Sep 26, 2019For the Receiving side, we will use an Arduino Uno with LoRa module and 16×2 LCD Display module. The circuit diagram to connect the Arduino with LoRa and LCD module is shown below . The connections are the same as Trasnsmitter except the LCD module connected with Arduino. Complete connections are given in below table.
Wireless RF Communication using nRF24L01 Module
Aug 01, 2019Designers use many wireless communication systems like Bluetooth Low Energy (BLE 4.0), Zigbee, ESP8266 Wi-Fi Modules, 433MHz RF Modules, Lora, nRF etc. And the selection of medium depends on the type of application it is being used in. Among all, one popular wireless medium for local network communication is the nRF24L01e modules operate on 2 (ISM band) with baud
