NCD set out to build the world’s best AC Current Monitor Sensor for MQTT over WiFi. What we’ve come up with is a high accuracy, high reliability, and easy to use WiFi enabled AC Current Monitor able to connect and transmit to any MQTT Broker. This product integrates a 100 Amp or 200 Amp split core current sensor to sample the current at a high rate to obtain multiple data samples and broadcasts the RMS Current at user defined intervals over WiFi to an MQTT Broker.
This AC Current Monitor Sensor for MQTT over WiFi was developed to work with any MQTT Broker. As one of the world’s most popular IoT protocols, MQTT is an essential, easy to use tool for viewing data from 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 AC Current sensing, nothing compares to the ease of use, low price, high accuracy, operational temperature range, or security features we at NCD have to offer.
To begin, access the product user guide under resources to learn how to use MQTT and this sensor in conjunction.
Note that this sensor will need to be externally powered and is capable of using a 6-32VDC power supply.
MQTT.fx is an application that can stream sensor data from a MQTT Broker. This simple feature as shown to the right provides effortless temperature and humidity 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 to be 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 and humidity data from the sensor is displayed every 2 seconds.
This device sends data periodically based on user-preset timing intervals. As this sensor does not use batteries, the transmission interval does not need adjusted with the intention to save battery life.
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.
Not for use in outdoor applications or for use in excessive temperature conditions. Prolonged exposure to extreme humidity conditions may damage this device. The sensing element is rated for use for 5 years and may be replaced. NCD Warranty does not cover use in excessively smoky environments under any circumstances.
