If you want to create a dirt cheap Temp sensing system, consider this as a possibility...
WeMOS device with a DS18b20 hat, have a look at Aliexpress. You load the tasmota firmware onto the WeMOS and you have a fully functioning Temperature mqtt device.
Total price for mine are $5AUD for each node. Equally you could make your own like I did, there is ability in the code to add multiple sensors onto the 1-wire if needed.
If you need any more info dont hesitate to ask, it really is simple.
