Implementation of Android application on rabbit droppings compost fertilizer processing tool

The sewage waste from a farm, in this case, a rabbit farm, is a byproduct that rabbit breeders have not been able to optimize. The collection and processing of rabbit manure to make it into a compost fertilizer product would require a system that can conduct the work mechanically and be controlled wirelessly. The system is made up of an ESP32 as a process controller for the soil moisture sensor and an ultrasonic sensor to collect rabbit droppings that are directed by a DC motor conveyor and driven by the blynk application. And the maximum distance required for the tool to maintain control over the smartphone is approximately 20 meters.
