Temperature Monitoring

Temperature data from around the space is to be log via Cacti.
Sampling done with DS18S20 1-wire digital thermometer, these can be daisy chained of the other arduino and MQTT devices.
Aim to publish a standard format MQTT message that a script on Holly will decode and push to cacti

Posible Arduino to hook into

• Gatekeeper in members box room (arduino, ethernet)
• LED Matrix in studio (arduino mega, ethernet)
• Vending Machine in workshop (nanode)
• Energy Monitor in blue room cupboard (XRF)

Old Notes

• Temp sensors dotted around space
• Nanode again
• Small wireless units or daisy chain of dalas one wires?
• Humidity sensor's?
• Push to cacti
• Query from irc
