lorawan temperature sensor humidity sensor iot wireless sensor

This page discusses the design and development of LoRaWAN Temperature Humidity Sensors, including the hardware components used. It also provides a list of certified LoRaWAN Temperature Humidity Sensor manufacturers or vendors.

Introduction

This article explores Temperature/Humidity sensors based on LoRaWAN. LoRaWAN is a low-power, long-range wireless system that operates in various frequency bands worldwide.

These temperature/humidity sensing devices find applications in:

Food/vegetable storage and transportation
Manufacturing labs
Server rooms or data centers
Climate monitoring
Smart factories and buildings
And more

LoRaWAN Temperature Humidity Sensor Design

The figure below shows a block diagram of a LoRaWAN Temperature Humidity Sensor. It consists of a sensor, a microcontroller unit (MCU), and a LoRaWAN transceiver. The device connects wirelessly to the LoRaWAN network via a gateway.
