Data logging onto Cloud of 50nos DHT22 and PIR

HI -

I'm working on a project, for an office space to monitor each occupant work space RH and temperature, and log the data on to cloud, but there is a constraint that no cable should be laid(ex: for looping the routers).

I'm planning to use ESP 8266 12e - 50nos and 8 routers, from router want to use GSM module but not sure if the router could be interfaced with GSM.

Pl suggest if there are better configuration.

Best,

Ramesha

Seems a job for e.g. a WeMos D1 mini + RH/temp sensor.

Arduino+WiFi+flash, all in one.

Thanks, but my challenge further up the configuration - how do I, take it to cloud with GSM(as I'm constrained to use routers)
