stm32f103zet6 mq135

STM32F103ZET6 is a microcontroller from STMicroelectronics' STM32 family, based on the ARM Cortex-M3 core. It has 512 KB flash memory and 64 KB SRAM, and supports various communication interfaces such as SPI, I2C, USART, and CAN.

MQ135 is a gas sensor that can detect the presence of gases such as ammonia, nitrogen oxides, benzene, smoke, and carbon dioxide. It uses a small heater element to heat the sensing element, and then measures the change in resistance of the element when it comes into contact with the gas.

To use the MQ135 with the STM32F103ZET6, you can connect the sensor to one of the microcontroller's analog input pins and read the analog voltage output of the sensor. You can then use this voltage reading to calculate the concentration of the gas being detected. There are several libraries available for interfacing with the MQ135 sensor on the STM32 platform, such as the MQ135 library for Arduino, which can be adapted for use with the STM32F103ZET6.
