Sensor-Tag(Arduino-HDC2080-RFM98-ESP32)

A sensor tag M2M network using atmega328p as a microcontroller and LORA RFM98 as a transmitter module to sense humidity and temperature.

Main Features

• This module will sense the data and send it to the gateway at aa predefined interval.
• Works on 3.7 li-Ion battery.
• Power efficient sensor node with battery indication.
• When antenna is connected to the module then the node can transmit upto a range of 1 kilometer.

Hardware

• 3.3V 16MHz (with ATmega328P)
• 3.3V RFM98 module
• TI HDC2080 temperature and humidity sensor
• ESP32

Materials

• Arduino code with sleep mode and the rfm connections.
• Similar ESP32 code with sleep mode and transmission btu it consumes more power as compared to Arduino328p.
• Reciever code.

Programs attached(Arduino IDE Code)

Project 1

• Arduino with battery status contains the code for Arduino328p with rfm98 and HDC2080 which senses the temp and humidity and the battery status and send it to the esp32rfm gateway.
• ESP32 receiver RFM is the gateway code for Arduino sensor node.

Project 2

• BLE Sender is the ESP32 code to transmit data using inbuilt BLE in ESP32 to a BLE gateway
• BLE Gateway is the BLE gateway program for esp32 BLE sender.
