(Click on highlighted city for photo of compromised sensor):
• A sensor in Tahoe City, Calif., sits near a paved tennis court and is right next to a “burn barrel” that incinerates garbage.

• A sensor in Redding, Calif., is housed in a box that also contains a halogen light bulb, which could emit warmth directly onto the gauge.
