The team has had a few challenges on the circuit boards but the device they are building and using with their bat houses will contain three main sensors: two infrared tripwire sensors to monitor bat activity in and out of the boxes, two temperature sensors accurate to +/- 0.5 ºC, and one ambient light sensor. These sensors will allow us to monitor the amount of activity depicted at different times of day, in relation to sunlight exposure and daily temperatures. Tripwire sensors are more relevant to our project than frame sensors because they are only triggered when a live organism moves it. Framed sensors are automatically activated when something enters the frame, such as a leaf, therefore making data less accurate. The temperature probes also ensure that only hot-blooded organisms are recorded as to not alter data collection.
