On the configuration you should be automatically see the HLK-RM04 Serial2Net setting page. The username is admin and the password is admin as well. Once we are connected to the network and our device has obtained an IP address from its DHCP we are opening the configuration page of the module by typing the following IP address to a new browser window 192.168.16.254 We are connecting our device to this wireless network by using the password: 12345678 When it is powered with the default configuration the HLK-RM04 WiFi module acts as a wireless access point which can help in order to configure it properly for our application.īy using the wireless network discovery from a PC or tablet or even a smartphone we are looking or a SSID named HI_LINK_xxxx (e.g. The idea of wireless temperature meter can be improved and converted into a complete weather station or it can be used as a low cost WiFi interface to control various devices around your house just by powering up the Arduino based device.

TIP: You can create your own Arduino compatible board by using just an ATMEGA328 μP unit and some peripheral parts or you can use Arduino compatible devices like the Redesign Pro Mini atmega328 5V which can be found on for about 2,00 €. My approach is much cheaper since you can connect any Arduino compatible device even the ones without the USB connection circuit (boards like Arduino Pro Mini) to the TCP/IP network using wireless connection. The problem is that in order to read the environment temperature you have to connect the device to the computer using USB connection you have to use an Ethernet shield or a WiFi shield in order to connect the device to TCP/IP Network. There are a ton of examples on the internet about it. Arduino can be easily turned into a thermometer just by using the LM-35 sensor (or any other temperature sensor).
