Displaying Temperature and Humidity Data on Ubidots using esp32 and NCD wireless Temperature and Humidity Sensor .
Introducing NCD’s long-range wireless temperature humidity sensor, boasting up to a 28 Mile range using a wireless mesh networking architecture. Incorporating the Honeywell HIH9130 temperature humidity sensor, transmits highly accurate temperature and humidity samples at user-defined intervals.
The on-board temperature sensor is rated for -25°C to 85°C or -13°F to 185°F and the humidity sensor is rated for 0 to 100% RH. Powered by just 2 AA batteries and an operational lifetime of 500,000 wireless transmissions, a 10 years battery life can be expected depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
With an open communication protocol this IoT wireless temperature humidity product can be integrated with just about any control system or gateway. Data can be transmitted to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino. Sensor parameters and wireless transmission settings can be changed on the go using the open communication protocol providing maximum configurability depending on the intended application.
The long range, price, accuracy, battery life and security features of Long Range Wireless Temperature Humidity Sensor makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.

ZigBee Wireless Communication Mesh Networking is simply the hottest wireless technology of our time. Period. It’s fast, it’s very easy to use, highly reliable, and self healing. Three components are required for the ZigBee Mesh Network, the Coordinator (C), the Router (R) and the Endpoint (E). Your computer can speak to a ZigBee Mesh Network using a Coordinator. Think of the Coordinator as the interface to a ZigBee Mesh Network. NCD Coordinators are equipped with a USB Interface. This ZigBee Coordinator mounts as a Serial Port on your computer, and you will develop software that sends Serial commands at 115.2K Baud. The primary job of a router is to bridge the wireless gap between your computer (the Coordinator) and the device (Endpoint). If the Coordinator cannot speak to the Endpoint device because it is out of range, a Router can be used to bridge the two devices together. Endpoints are simply devices. With regard to NCD products, Endpoints can be relay controllers, data collection devices, PWM devices, and much more.

USB ZigBee Coordinator Your computer can speaks to a ZB ZigBee Network using a Coordinator. Think of the Coordinator as the interface to a ZB ZigBee Network. NCD ZigBee Coordinators are equipped with a USB Interface. USB Coordinators mount as a Serial Port on your computer, and you will develop software that sends Serial commands at 115.2K Baud. Only ONE Coordinator should be installed within a wireless ZB ZigBee Network. Two types of Coordinators are available. AT and API. Normally, AT coordinators are used. AT coordinators use Terminal-like AT commands to speak to a ZB ZigBee Network. They are easier to use than an API coordinator. An API coordinator uses a string of carefully chosen bytes and checksums to communicate data to a ZigBee networking. API coordinators are harder to use, but can communicate and switch between devices much faster. This page will introduce you to AT coordinators. You can choose between AT and API firmware at checkout.
The ESP32 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. This ESp32 IoT Module combines Wi-Fi, Bluetooth, and Bluetooth BLE for a variety of diverse applications. This module comes fully-equipped with 2 CPU cores that can be controlled and powered individually, and with an adjustable clock frequency of 80 MHz to 240 MHz. This ESP32 IoT WiFi BLE Module with Integrated USB is designed to fit in all ncd.io IoT products.
Monitor sensors and control relays, FETs, PWM controllers, solenoids, valves, motors and much more from anywhere in the world using a web page or a dedicated server.
We manufactured our own version of the ESP32 to fit into NCD IoT devices, offering more expansion options than any other device in the world! Integrated USB port allows easy programming of the ESP32. The ESP32 IoT WiFi BLE Module is an incredible platform for IoT application development. This ESP32 IoT WiFi BLE Module can be programmed using Arduino IDE.
Hardware :
- ESP-32
- IoT Long Range Wireless Temperature and Humidity Sensor
- I2C Cable
- PARTICLE ELECTRON OR PHOTON COMPATIBLE I2C SHIELD
- ZigBee Coordinator Long Range Wireless Mesh Modem with USB Interface
Software Used:
- Arduino IDE
- Ubidot
Library Used:
- PubSubClient Library
- Wire.h
This library provides a client for doing simple publish/subscribe messaging with a server that supports MQTT
For more information about MQTT, visit mqtt.org.
The latest version of the library can be downloaded from GitHub
The library comes with a number of example sketches. See File > Examples > PubSubClient within the Arduino application. Full API Documentation.
The library uses the Arduino Ethernet Client api for interacting with the underlying network hardware. This means it Just Works with a growing number of boards and shields, including:
- Arduino Ethernet
- Arduino Ethernet Shield
- Arduino YUN – use the included YunClient in place of EthernetClient, and be sure to do a Bridge.begin() first
- Arduino WiFi Shield - if you want to send packets greater than 90 bytes with this shield, enable the [MQTT_MAX_TRANSFER_SIZE] (https://pubsubclient.knolleary.net/api.html#configoptions) option in PubSubClient.h.
- Sparkfun WiFly Shield – when used with this library
- Intel Galileo/Edison
- ESP8266
- ESP32 The library cannot currently be used with hardware based on the ENC28J60 chip – such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an alternative library available.
The Wire library allows you to communicate with I2C devices, often also called "2 wire" or "TWI" (Two Wire Interface),can download from Wire.h
-
Wire.begin() Begin using Wire in master mode, where you will initiate and control data transfers. This is the most common use when interfacing with most I2C peripheral chips.
-
Wire.begin(address) Begin using Wire in slave mode, where you will respond at "address" when other I2C masters chips initiate communication.
-
Wire.beginTransmission(address) Start a new transmission to a device at "address". Master mode is used.
-
Wire.write(data) Send data. In master mode, beginTransmission must be called first.
-
Wire.endTransmission() In master mode, this ends the transmission and causes all buffered data to be sent.
-
Wire.requestFrom(address, count) Read "count" bytes from a device at "address". Master mode is used.
-
Wire.available() Retuns the number of bytes available by calling receive.
-
Wire.read() Receive 1 byte.

- Download and include the PubSubClient Library and Wire.h Library.
- You must assign your unique Ubidots TOKEN, MQTTCLIENTNAME, SSID (WiFi Name) and Password of the available network.
- Compile and upload the Ncd_Temperature and Humidity Sensor.ino code.
- To verify the connectivity of the device and the data sent, open the serial monitor.If no response is seen, try unplugging your ESP32 and then plugging it again. Make sure the baud rate of the Serial monitor is set to the same one specified in your code 115200.
- Create the account on Ubidot.
- Go to my profile and note down the token key which is a unique key for every account and paste it to your ESP32 code before uploading.
- Add a new device to your ubidot dashboard name esp32.
Click on devices and select devices in ubidot.
Now you should see the published data in your Ubidots account, inside the device called "ESP32".
- Inside device create new variable name sensor in which your temperature reading will be shown.
-
Create dashboard in ubidots
