Step 1: Remove the four screws from the front of the remote temp/humidity sensor and open the plastic case
The resistor is non-directional, but the diodes need to point in the correct direction.
Be careful to place them with the black bands on the ends as shown. ,, You can use a razor or X-Acto Knife. ,, Instead of the electricity flowing though the trace, it will flow through the diode that we soldered over the gap. , At this point, we should have done all that is crucial to making this work.
We will add additional components in the next few steps to help suppress interference on the traces going to the sensors.,,,,, Here's what mine looked like after adding all of the components.
Note:
The closest value that i had to 470 nF was 140 nF Capacitors.
I measured them with a voltmeter and determined that they were roughly 220 nF.
By putting two of them in parallel (back to back rather than one after another), I was able to get close enough with 440 nF. , I had to re-arrange the two largest capacitors so that the cover would fit on without forcing anything closed. ,,,, My data updates approximately every 3 seconds., -
Step 2: IMPORTANT: If batteries are installed
-
Step 3: be sure to remove them now.
-
Step 4: Remove the screws holding the circuit board in place
-
Step 5: Solder a wire as shown in order to create a connection ("jumper") between these pins.Once you have done this
-
Step 6: the data to the emitter does not arrive anymore; therefore
-
Step 7: it is necessary to add add some more components.
-
Step 8: Solder the two diodes and resistor as shown.
-
Step 9: Turn the board over
-
Step 10: Carefully scrape the protective green covering off of the trace as shown to reveal the copper underneath.
-
Step 11: Scrape the copper off part of the trace to break the connection.
-
Step 12: Solder a diode over the trace to "bridge the gap".
-
Step 13: Check your connections.
-
Step 14: Turn the board over to the bottom again.
-
Step 15: Add the 470 nF Capacitor.
-
Step 16: Add the 10nf Capacitors as shown.
-
Step 17: Finally
-
Step 18: add the 100 nF Capacitors as shown.
-
Step 19: Almost there!
-
Step 20: Add electrical tape or heat-shrink tubing so that nothing shorts out.
-
Step 21: Replace the screws holding the circuit board in place
-
Step 22: Replace the batteries
-
Step 23: Close the plastic case and replace the four screws from the front of the remote temp/humidity sensor.
-
Step 24: Test it out.
-
Step 25: Congratulations: You've Finished!
