    Poultry Farm Environment Monitoring and Control

    Application Overview

    Measurement, control and maintenance of ambient conditions such as incubator temperature, humidity, egg storage room facilities and water levels on a poultry farm is crucial to minimize loss of livestock in event of equipment failure or changes in weather conditions.

    Various types of sensor inputs are connected to the battery powered DNT24 radio modules at various location in the poultry farm facility. The DNT24 radio modules are normally in a sleep mode and then periodically transmit the sensor readings to a host application – after which they go back to sleep to conserve power. The host application then determines what course of action to take based on these readings such as triggering alarms when the temperature range is exceeded or by turning the HVAC units on or off.

    Applicable Product Features

    The DNT24’s Frequency Hopping Spread Spectrum technology (FHSS) provides reliable RF communication over long distances on the poultry farms. The DNT24 Module with multiple I/O, sleep mode and auto-reporting on analog values for alarms capability, API for easy integration was an ideal choice for such an application. The low cost allows systems to be economically priced and finally the 2.4GHz allows world-wide deployment.
