Temperature and humidity program based on msp430f5529 [Copy link]

The experimental project uses MSP430F5529 as the main control, WiFi module to transmit data, DHT11 module to detect temperature and humidity, and also detects light conditions and toxic gas detection functions. The

microcontroller source program is as follows:
