Thanks in advance for your feedback. I am looking for suggestions on the following:
We would like to place a temp sensor in a cooler/freezer and have the sensor close a contact if the temp goes under or over a certian temp range ( -20C to 10C) or example. The sesnor will be wired/wireless to the camera I/O contact and we will manage the rest through the VMS.
Summary of requirments:
1- Wired/wireless Temprture sensor
2- Low power consumption
3- Can be placed inside a freezer/cooler (-20C to 20C operating temp)
4- Closes a contact when temprture goes above/below a set range.
5- Only hardware, No managment sotware needed
6- Low cost.
Thanks.
