Product SEN-00245 |

I bought one of these to monitor soil temperature in my garden and so far it has held up. I used heatshrink to build a cheaper (read: handy man special) version of DS18B20. It has faired well being submerged in moist-to-wet soil however over the past 14 days there have been 3 small, one-off, events where the temperature reading ended up being -196.6 F.
Readings are taken every 15min. and I have not yet confirmed if it might be a timing calibration issue or if my heat shrinking capabilities are sub-par (I’m going to bet the latter).
I’ll be buying up to DS18B20 for next growing season but can certainly find a few other uses for this type of sensor; namely indoor gardening. Great product when used within reason.
No public wish lists :(
