WiFi AC Current Monitor for MQTT
NCD set out to build the world’s best WiFi AC Current Monitor for MQTT. In doing so, NCD now incorporates a precision Split Core AC Current Monitoring Sensor with a WiFi Module and Control Board. This WiFi AC Current Monitor makes it easy to monitor AC current flowing through the sensor and receive alerts when the AC current value exceeds the preset limits.
This WiFi AC Current Monitor for MQTT samples current at a high data rate and calculates the RMS value. Note that in order to get any current readings on the display other than zero, the voltage of the wire being measured must exceed 1.5 volts. Next, the device sends a data transmission to a MQTT Broker. The user can then monitor the AC current flowing through their equipment from any location via WiFi by connecting the MQTT.fx application to the Broker that they are using.
This WiFi AC Current Monitor was developed to work with any MQTT Broker. As one of the world’s most popular IoT protocols, MQTT is an essential tool for a monitoring a wireless sensor device. Therefore, connectivity of the NCD ecosystem of IoT wireless sensors remains a top priority for the NCD engineering team.
When it comes to current monitoring, nothing compares to the ease of use, low price, high accuracy, operational temperature range, or security features we at NCD have to offer. Note that this device will need to be externally powered and is capable of using a 6-32VDC power supply.
To begin, access the product guide under resources to learn how to use MQTT and NCD’s AC Current Monitor in conjunction.
Applications
- Wireless AC Current Monitoring
- Industrial Current Monitoring

- Key component of predictive maintenance
Monitor AC Current with MQTT.fx
MQTT.fx is an application used to stream sensor data from a MQTT Broker. This simple feature as shown to the right allows effortless AC Current sensor data monitoring. Customize how this data is displayed in JSON format when configuring the sensor.
Another useful feature of the MQTT.fx application, a cloud update topic, allows the user to configure 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.
Update the interval of transmission by publishing the following JSON command to the cloud update topic: {“interval”:3000}. This happens to be what was done in the visual to the right. After this command is given, new AC current data from the sensor is displayed every 3 seconds.
Transmission Interval
This device sends data periodically based on user-preset timing intervals. As this sensor does not use batteries, the user does not need to adjust the transmission interval with the intention to save battery life.
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.
