Introduction to Wi Fi Network Noise Sensor

Wireless network noise sensorsound level meterJHM-NS02 is equipped with a Wi Fi module JHM-MFFI.

Technical parameters of network module: IEEE 802.11 standard. Users can define their own IP, port address, access hotspot, password, as well as set the destination IP and port for delivery!

Module Name: JHM-MFWIFI

----------------------------------------------------------------------------------------------------------------------------------------------------

JHM-WIFI module, powered by DC12V, IEEE 802.11 standard. Working in STA mode, IP/UDP communication mode.
The user uses the matching serial communication cable, with serial port baud rates of 9600 and 8 n、 1. The module can be configured using the serial assistant software through the computer serial port,

All command characters are capitalized, and the specific instruction operations are as follows:
a: Sending a HELP? (Enter) Give the module, and the module returns commonly used operation commands to help the operator remember them conveniently.
b: Sending CM+INFO=? (Enter), The module returns all information including the set IP, target IP, port, hotspot name, and password.
c: Sending CM+MYIP=? (Enter), The module returns its own IP address, enter CM+MYIP=IP=192.168.0.1 (Enter), and the module IP is changed to the current IP address.
d: Sending CM+OBIP=? (Enter), The module returns the IP address of the noise transmission target, input CM+OBIP=192.168.0.100 (Enter), the noise data transmission destination

Change the address to the current IP
e: Send CM+PORT=? (Enter), Query local and target port addresses, with port lengths below 5 bits (greater than 4000).
f: Sending CM+HOTA=? (Enter), Search for the name of the access hotspot, enter CM+HOTA=abcdeefg (Enter), abcdeefg wants to access as the hotspot name.
g: Sending CM+PASS=? (Enter), Query and set the access hotspot password, enter CM+PASS=(Enter) as the access hotspot password.

Noise data format: CM+NS02=056.7 (Enter), '=' followed by 3 integers and 1 decimal is the noise value
