This week I started to gather background information for my project. I need to decide between an active or passive infrared sensor. An active sensor is better for my project because active sensors will work in the dark and the time of day does not matter. This is crucial in my project because the majority of the sensing is to get readings of intruders during the nighttime versus the daytime. Along with that, I started to research solar collection and photo voltaic cells and how they can link to an LED.
