Telemetry System for Highland Tomato Plants Using Ubidots Platform

In a telemetry system, data related to the agriculture product can be monitored through the cloud server without physically being at the farm location. This project aims to develop a telemetry system for monitoring significant parameters of highland tomato plants to produce high-quality fresh tomatoes. The system is equipped with a light intensity detector, a single-chip humidity-temperature sensor, and a soil moisture sensor controlled by Raspberry Pi. The data collection is conducted at MARDI Agrotechnology Park, Cameron Highlands, to measure the parameters of red beefsteak tomatoes. The developed system can monitor the measured parameters via Ubidots dashboard and trigger the irrigation system when the soil moisture is below the optimum level. The user will be notified when the surrounding temperature is higher than the threshold value. Results show that the telemetry system can be viable for monitoring tasks. The threshold values of the highland tomato plant parameters are observed, with a minimum moisture level of 60% and a maximum temperature of 29°C to increase the tomato yield.
