The popular IoT platform ThingsBoard has many options for integrating data from other systems. On the blog, we have already described the methods of the Pull model using a custom HTML widget that periodically retrieves the latest data from Watmonitor, as well as a form of direct writing of device telemetry to ThingsBoard from the Node-RED tool...
Node-RED is a tool that enables data acquisition, transformation and visualization in real time. It is designed as a low-code platform for creating event-driven applications. The basic principle is to compose blocks (nodes) into flows that provide the required automation. It is used not only in small projects, but also in large scalable industrial...
Today, we're excited to showcase the integration of the Watmonitor project (a smart level meter) with ThingsBoard – a powerful open-source IoT (Internet of Things) platform trusted by both hobbyists and enterprises for industrial and corporate applications.
Watmonitor is a web interface for a water level meter (PHP application) that allows you to collect data from a sensor node. which performs measurements in a dug, drilled well, or retention tank, cesspool. This universal web interface is also suitable for measuring and visualizing the height of bulk materials. It can be used with any DIY sensor or...
If you are using Watmonitor (a web interface for a level meter) from Your-IoT to measure the water level in a well, retention tank, or measure the height of bulk materials in a silo, storage tank, you may have encountered a limitation of Watmonitor if you wanted to use multiple sensor nodes. Each instance of the Watmonitor interface is tied...
Watmonitor is a universal web interface for a water level meter that allows you to collect data from a sensor node that sends a differential or total water level at regular intervals, depending on the sensor used (ultrasonic, radar, pressure, capacitive, optical, doppler, inductive). Each sensor has its advantages and disadvantages in terms of use...
LoRa is a technology for transmitting data over long distances, which also excels in its resistance to interference or data transmission even through obstacles, where other technologies would fail. LoRa is excellent for use where we do not have WiFi or another form of internet connection and we want to transmit data. Today we will show a LoRa...
WM_Mini (Watmonitor Mini) is a small PCB measuring 30 x 28.6 mm. It has two mounting holes with a diameter of 3 mm, a communication bus with two data channels and 3V3 power supply. As well as a 2-pin interface for connecting an external 5V power supply for recharging the battery (external power supply, solar panel), while it can...
