Vehicle Environment Monitor helps keep your dog safe
Pets bring an untold amount of joy into our lives, but unfortunately they aren’t allowed to go everywhere that humans are. Of course this makes sense in many situations, but if you’d like to take your dog with you wherever you go, this means occasionally leaving poochie in the car. Along with keeping the sunroof and windows open, this project’s author also came up with a transmitter and receiver to monitor the temperature inside of the car with a series of LED pulses.
The car unit consists of an Arduino Mega, along with a temperature sensor and LoRa transciever. The receiver takes this wireless information, which can be reliably read at a range of 250 meters (820 feet) in an urban environment, and gives the user a series of blinks to assure Max’s (the dog) human that he’s safe and comfortable.
