Ambient Temperature Sensor
Caleb M.
Victoria, BC
September 6, 2025
I live in Victoria where the weather changes all the time, and this little sensor has been a game-changer for my daily drives. It reads the outside air and tells my climate control what to do, so I'm always comfy without thinking about it. As a pragmatist, I appreciate things that just work, and this does exactly that. It feels very reliable, and it's nice not to have distractions while driving with my kid in the car. Overall, it's a solid upgrade that makes life easier.
- Pros: It was super easy to install with just basic tools, and it works perfectly with my car's system to keep the inside temperature just right without any fiddling. The courier even called ahead, which was a nice touch.
- Cons: It seems a bit pricey for what it is, and I wish it came with a bit more detailed instructions, though the manual was okay.
