Temperature Monitor for RV (post 4 of 4)

This photo taken with camera near pavement angled up.
FSC and sensor are just barely visible behind the lowest part of the bumper trim.
We want to get an accurate "overnight low" and this is a good location for that.




Viewed straight on, FSC can't be seen.









Let's look at the monitor. The upper digital readout is the monitor's own temp sensor (vehicle interior).

Channel select 1 then 2 then 3 and watch lower readout.
#1 is our exterior front location and we expect lowest of all readings there.
#2 is our underhood and clearly we expect higher readings.
#3 no sensor at this time

What was the food container "bottom" of FSC is now securely screwed to lowest sheet metal I could find as far forward on the vehicle as I could find: don't want radiator affecting sensor.
(I changed to using metal screws here after having two separate tape attachments, one on perfectly cleaned metal, one on perfectly cleaned plastic "drop off".)




Photo shows hooking tab of FSC lid on hidden side first, then swinging lid up into place. Last step will be snapping end tabs into place.
A fairly secure closure!

Prep for sensor #1 (Exterior)

Drilled 2 holes in Food Storage Container (FSC) base. Size for round-head Robertson metal screws. Mounting surface will be sheet metal. Base has no ventilation holes, keep watertight if possible.




Top view. Sometimes you might be looking down through the translucent snap-on lid to see what was good to eat. Not today!

Our temp sensor is stuck to the underside of the FSC using double-sided tape (here using little squares). Four ventilation holes have been drilled. This "top" will be the bottom in our install.




This view shows the sensor face-up with its back stuck to FSC lid. The sensor can still be taken apart for battery replacement.
FSC has a secure closing mechanism.

General concept: Install a "Monitor" inside the RV (probably on the dash) and install 2 or 3 "Sensors" outside but attached to the vehicle.







Found this reasonably priced "Indoor/Outdoor Wireless Thermometer and Hygrometer" at local discount store.
- digital C or F display of current, Max and Min
- 3 channel support
- 30M transmit range
Labeled: "National Geographic".




Install sensor #2 first, as it is easier.
Find a suitable location underhood.
Clean surface well, attach using double-sided tape.

Location chosen was out of the path of heated engine air.
