Datalogger for recording pond temperature
As the cold weather looks set to continue for a couple of weeks, today I reconnected the temperature probe to the old pond.
It’s been out of action for a while after I chopped the cable linking the logger to the probe last year (lawn mowing – typical).
The ‘probe’ itself is simply a 30 m length of wire with a thermocouple in the end.
The data are brought to the computer by a myPCLab datalogger (above).
Measurements last year showed that, at night, water in the pond was up to 10 degrees warmer than the surrounding air.
