A multi-checkpoint type clustered animal counting device is proposed, which is capable of providing a counting function that can be used for statistically determining the number of animals (such as fruit flies) within a region such as farmland or garden. The proposed animal counting device is characterized by the utilized to at least two object sensors, wherein the first object sensor is disposed at a first checkpoint while the second object sensor is disposed at a second checkpoint, and wherein the first object sensor is initially set to power-on state while the second object sensor is initially set to power-off state and can be switched on only when the first object sensor is triggered. When the second object sensor is triggered, the counting operation will increase the output count number by one. This feature allows a more accurate result and can help save power consumption.

A front-end gateway unit is designed for integration to a remote ecological environment monitoring system that is equipped with a wireless sensor network (WSN) system installed at a remote site, such as a farmland or a garden, for the purpose of allowing the WSN system to exchange data with a back-end host server via a wireless communication system. The front-end gateway unit is characterized by the capability of using either the WSN system or a built-in sensing module for collecting ecological data, and the capability of combining geographical location data in the ecological data. This feature allows the collection of a comprehensive set of ecological data (including geographical location, temperature, humidity, sunlight data, wind speed, and pest number) for transfer to the back-end host server, such that research/management personnel at the local site can conveniently browse these ecological data and learn the ecological conditions of the remotely monitored area.

Front-end gateway unit for remote ecological environment monitoring system

A wireless-linked remote ecological environment monitoring system is proposed, which is characterized by the use of a sensor network such as WSN (wireless sensor network) installed at the remote site for collecting ecological data, and the use of a public wireless communication system such as GSM (Global System for Mobile Communications) for transferring all the collected ecological data to a back-end host server unit where the ecological data are compiled into webpages for posting on a website. This feature allows the research/management personnel to browse the ecological data simply by linking a network workstation via a network system such as the Internet to the website, without having to travel to the remote site and collect ecological data by human labor.
