A system to monitor water PH, temperature, and ammonia levels in Fish ponds using Industrial IOT
Abstract
In aquaculture, the quality of the pond water in the production systems can significantly affect
the aquatic organism’s health and the costs associated with getting a product to the market.
However, suppose the PH level, ammonia level and the temperature of the pond water are not
suitable. In that case, the following situation could occur, primary production, as well as natural
feed for fish, will not be sufficient, the growth of fish will be slow, and much more
supplementary feed will be required. Therefore, it is necessary to clearly understand how these
water quality parameters are affecting fish production in any fish pond system, and hence
monitor them in real time.
In this project report, we exploit and utilize the existing embedded systems and IoT technologies
as a foundation for development. The algorithm to do this involves the use of microcontrollers,
sensors, a cloud platform, mobile and web dashboards, and an actuator idea to achieve real-time
monitoring of the PH levels, ammonia levels and temperature of the pond water.
Also in this report, we show the use a water pump as an actuator to enable prompt action and
measures to be taken in case of any anomalies or deviations from the standard parameter
thresholds. This helps the fish farmers to make informed decisions regarding the water quality or
resource management.
To monitor water quality in real time, we placed the PH sensor, the DHT temperature
sensor, and the Ammonia (MQ gas) sensor connected to Arduino in water of various
chemical and physical properties and observed how their values varied. We calibrated the
sensors used in the system design to achieve the precise values. The results were then
displayed on Blynk mobile applications and a web dashboard after the system connected to
the internet. The captured data can be accessed anywhere and at any time remotely as long
as the internet bandwidth is available.
In order to analyze the performance and efficiency of the system, a viable methodology was used
where the components of the system were obtained, the system designed and tested throughout
the process.
