The researchers designed a device called Project ECO to help address the problem of deforestation. Project ECO uses a wireless camera and enhanced sensor detection system including vibration, smoke, flex, and temperature sensors to remotely monitor and detect illegal activities in forests like logging and farming. The device was constructed using an Arduino board connected to the various sensors and a Bluetooth module. It was programmed using Arduino software and tested for its effectiveness in protecting forests and biodiversity from human activities that cause deforestation.
