Advantech WISE-4220-S231 IoT Wireless Module

Today, I will be sharing the advantages of using IoT devices such as the Advantech WISE-4220-S231 wireless sensor. The  WISE 4220 series is an Ethernet-based wireless  IoT device.  What makes this device particularly useful is that its I/0 module is removable and can be replaced with other variants for different applications. Below are the listing of available I/O module for the WISE-4220 series

1. S231 - built-in temperature and humidity sensors.
2. S214 - 4 analog inputs and 4 digital inputs.
3. S250 - 6 digital inputs, 2 digital outputs and 1 rs-485 input.
4. S251 - 6 digital inputs and 1 rs-485 input.

What we have on-hand is the WISE-4220 with S231 variant. Powering the module is simple. It accepts voltages ranging from 10Vdc to 50Vdc. How convenient is that right? Just wait for a few seconds after powering the module and it will start broadcasting its SSID and ready to accepts WiFi connections. You can use your own cellphone or pc to access the wireless web interface. WISE-4220 can be also configured to connect over a wireless network. Data transmission uses the industry standard TCP Modbus protocol. Accessing the module anywhere is much easier as long as you are within the same network.
