DASH7

Dash7 is a type of technology that lets devices talk to each other. It does this by sending out very low power radio signals that can be picked up by other devices. The devices then use this signal to communicate information like sound, images, and data. This makes it easier for devices to work together and do things like automatically open a door when you get close. It's like when you say hello to someone and they recognize who you are and say hello back!
