I'm trying to predict when a peat moss pile is likely to undergo spontaneously combustion. Currently, it's a full-time job for someone to punch holes in piles and insert probes to take periodic temperature readings. In addition to being cumbersome and time-consuming, the holes introduce oxygen, which tends to escalate temperature increase.
I was hoping to find a source of cheap wireless temperature transmitters. During processing, it's likely that most will be recovered, but it's also likely that a lot could be damaged.
These could be inserted as deep as 10' into piles of harvested sphagnum moss. Bluetooth would probably work, but 433MHz could also work.
Something like a AcuRite 06002RM Wireless Temperature and Humidity Sensor would be OK, but it will be expensive to have them in 1000+ piles and there's also a possibility that the reader will pick up signals from adjacent piles.
Something that could be assigned a unique address would be ideal.
I was thinking that whatever we use could be inserted into a sealed PVC pipe for protection from the elements and to allow easy retrieval before the pile is transferred by simply pulling out the pipe.
