For those looking for a box trap sensor (electronic trigger)

箱罠センサー 電子トリガー

A box trap widely used for catching wild boars and deer. It is common to operate with a physical mechanism, but in recent years, the capture mechanism using sensors has been attracting attention and has been introduced in many areas.

Various types of traps are already being sold by various companies, but for those who are used to traditional box traps, they may feel intimidating. However, if used wisely, it is possible to improve the capture rate and work efficiency.

* This time, we will explain it separately from the " trail camera ", which is installed next to the box trap and records the state of the trap.

Capturing using a box trap + sensor

The box trap uses bait to lure the beast into the cage, and when the beast enters the cage, the mechanism activates and the door falls.

A typical box trap has a physical mechanism, such as a door falling down when a beast touches a mechanism inside the trap (kicking string, footboard, etc.).

For example, in the case of the method using a kick string, when a beast touches the string stretched inside the box trap, the wire or string that hangs the door comes off and the door closes.

On the other hand, in the case of traps that use sensors, sensors such as infrared rays detect when a beast has entered the trap. There is no need to prepare a kick string, and the lack of it makes it possible to weaken the beast's vigilance. In addition, it also helps to reduce the labor of the device.

The mechanism that the door automatically falls by the sensor

Infrared sensors are mainly used for this mechanism. The sensor housing and the string that hangs the door can be connected, and it is common to attach the sensor housing to the top or side of the box trap.

By the way, infrared rays are a type of electromagnetic waves emitted by objects and living things that have heat. Although this cannot be seen with the naked eye, the inside of the infrared sensor is designed to convert incident infrared rays into electrical signals. This mechanism is widely used as various sensors such as motion sensors.

By applying this to a box trap mechanism, when an object with a temperature difference compared to the ambient temperature moves within the sensor's sensing range, the sensor senses this, and the string that hangs the door comes off the sensor housing. The door is designed to automatically drop.

Application examples using IoT

Recently, attempts are being made to combine sensors and IoT to help capture them. IoT is to connect things that were not connected to the internet before to the internet.

For example, an infrared sensor detects that a beast has entered the trap, and the camera starts shooting at that timing. It will be possible to remotely check the images captured by the camera using a personal computer or smartphone via the Internet.

Furthermore, in order to save the effort of remote monitoring by humans, attempts are also being made to automatically detect the type and number of beasts from images so that only the targeted prey can be captured automatically.

There are also application examples such as automatically sending e-mail notifications to mobile phones, etc., at the timing of detection by infrared sensors, and identifying areas with high population density by mapping capture locations in cooperation with GPS.

However, the more advanced the functions, the more cost and effort it takes to introduce the system, and if necessary, you have to prepare a separate SIM card for network connection. There is also the aspect that it is difficult to introduce in the land.

Inohoi Recommended Sensor Box Trap

Based on the above, for those who want to introduce a box trap with a sensor + box trap, we recommend the type that automatically closes the door with an infrared sensor instead of the type that utilizes IoT.

This product is a sensor supervised by a veteran hunter, and it is a sensor product with a simple setting method and a lot of achievements. Of course, it is also compatible with our Fare Asahi-style box trap .

Our box traps for wild boars and deer use a kick string system, but the setting of the kick string is surprisingly deep, and it may be difficult to catch adult animals that are highly cautious. Since tactics with beasts are important, an expert can adjust the material and tension of the kick string to match the target individual, but it may be difficult for beginners.

In such cases, we recommend the above sensor, and we have received reports that the capture rate has increased due to its introduction ( reference case ). The best feature is that you can set the height at which the sensor reacts in advance.

For example, if you use it in combination with our box trap big size single door (height 1.0m), if you set it in advance so that the sensor reacts at a distance of 60cm from the ceiling, if the height is less than 40cm The door closes only when it doesn't respond and a beast taller than 40cm enters.

Therefore, it is possible to set the door to drop only when a large adult animal enters, and it is also possible to prevent other small animals such as raccoon dogs from being captured.

Capture adults to reduce damage

In the case of wild boars, it is said that they give birth to an average of four offspring per year, depending on the environment and nutritional status. If the adults are not captured, the damage will not be reduced because the population will increase like a mouse.

Also, if only juveniles are captured, adults may learn from them and become wary of entering the trap. I think one way to deal with damage is to use the tools of civilization ( click here for the animal sensor product page ).
