WiFi Thermocouple Temperature Sensor for MQTT
NCD set out to build the world’s best WiFi Thermocouple Temperature Sensor for MQTT. In doing so, NCD now incorporates a precision Thermocouple Temperature sensor with a WiFi module and control board. This WiFi Thermocouple Temperature Sensor was developed to work with any MQTT Broker. As one of the world’s most popular IoT protocols, MQTT is an essential tool for monitoring a wireless sensor device. Therefore, connectivity of the NCD ecosystem of IoT wireless sensors remains a top priority for the NCD engineering team.
This NCD Industrial IoT WiFi Thermocouple Temperature Sensor for MQTT is capable of measuring extreme high and low temperatures. This product includes one 5SRTC-TT-K-24-36 K-Type thermocouple probe from Omega.com with a 1m, 24 AWG connection cable, rated for temperature measurement applications up to 260°C (500°F) with an accuracy of ±2.2°C. This wireless thermocouple device comes with K-Type connector, which can be used to connect a higher temperature range thermocouple if needed. This sensor has a built in hot and cold junction to provide highly accurate readings.
This WiFi Thermocouple Temperature Sensor is an ideal product for measuring high temperature in environments with hot equipment such as industrial boilers, industrial part-cleaning stations, furnaces, ovens, and casting units. With a tolerance of up to 260°C (500°F), this sensor gives precise temperature readings in an extensive list of high temperature environments. This WiFi Thermocouple Temperature Sensor for MQTT can also be used to simply monitor temperature in other environments as well such as food storage units, warehouses, assembly rooms, and more.
When it comes to temperature sensing, nothing compares to the ease of use, low price, high accuracy, operational temperature range, or security features NCD has to offer. Note that this sensor will need to be externally powered and is capable of using a 6-32VDC power supply.

Monitor Extreme Temperature with MQTT.fx
MQTT.fx is an application that can stream sensor data from a MQTT Broker. This simple feature as shown to the right allows effortless monitoring of thermocouple sensor data. Customize how this data is displayed in JSON format when configuring the sensor.
Another useful feature of the MQTT.fx application, a Settings Topic, can be used to configure the sensor settings using JSON formatted commands. This can be done in the open application and while the sensor is transmitting data, saving the time and effort of repeating the sensor setup process each time a setting needs changed.
The interval of transmission can be updated by publishing the following JSON command to the cloud update topic: {“interval”:2000}. This happens to be what was done in the visual to the right. After this command is given, new temperature data from the thermocouple sensor is displayed every 2 seconds.
Transmission Interval
This device sends data periodically based on user-preset timing intervals. Note that this sensor does not use batteries, therefore the user does not need to adjust the transmission interval with the intention to save battery life. This gives the user more leeway when choosing transmission intervals.
Security
At NCD, security always remains a top priority when developing new products. Therefore, this MQTT WiFi Sensor contains both WiFi and MQTT security protocols.
WiFi Security Features:
- WPA/WPA2/WPA2-Enterprise WiFi Security Protocols
- IEEE-802.11B/G/N WiFi Protocols
- DHCP or Static IP Managed Wireless Networks
MQTT Broker Security Types:
- TLS
- Basic AUTH
- OPEN
The security features that are accommodated by this WiFi MQTT Sensor are compatible with almost all IoT servers available. When configuring the sensor through the MQTT web interface, you are presented multiple options for increasing the security of your device such as a Soft AP username and password. Utilizing features like this are recommended as it adds one more layer of security to your WiFi sensor.
IoT Security should be taken very seriously. This is why NCD implements the best security features with our products. Be sure to check out the product user guide listed under the Resources Tab to learn more about how to configure the settings on your device.
Sensor Setup
Upon connecting to a MQTT WiFi Sensor, the NCD Web Interface will automatically open and be displayed. This easy-to-use interface allows for configuration of the MQTT Sensor over WiFi in one simple step without any software download or complicated set up procedure.
Using the product user guide for reference, the user can choose which network the device will connect to, create a password to be able to access the device, and customize the MQTT settings. These MQTT settings include server settings, client settings, and message settings.
