eZwink

eZwink

eZwink is a plug and play Wi-Fi module that sends and receives data from a server using MQTT Protocol. The data is sent with a network synchronized time-stamp and this approach eliminates the errors associated with manual logging of data and enables analytics and insight to be generated. Wi-Fi credentials, server details and GPIO’s are configured using eZwink mobile app. The GPIO status can be read in the mobile app and actuation can also be performed using mobile app. There is also one PWM control pin where the duty cycle can be changed using the same mobile app. The data can be sent to either a file in the server or to a database depending on the redirection provided in the script. RadioStudio can also provide the entire server solution at extra cost for customers who do not have a server ready for receiving data.
