ESP8266 with node red

It would need to be the RPi-ZERO-W (as that is the version that has WiFi). Also need a router.

Although the RPi-Z-W is not as powerful as the Pi-3B it should handle the MQTT traffic from your SRF-04 or SRF-05 without any problems. My IoT students have one each and do all sorts of things with them.

Raspberry Pi-Zero-W Mini-Tower

Just finished building a couple of mini-towers for my IoT Club. The idea is the towers can be kept in a cupboard at school and just brought out when I run the IoT Club. All I would need to do is plug the 6-port PSU into the mains and switch-on the Club's WiFi router. Should save a lot of time as previously I had to cobble together a number of Raspberry Pi(es),of various vintages, and then at the end of the session take the whole lot apart!!!
