    Using IO port trig trigger location, to the high level signal of at least 10us module automatically sends 8 40khz fang bo, automatic detecting whether a signal return. A signal return, a high level is output through the io port echo, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340m/s)) /2ranging, the measured object area of not less than 0. 5 square meters and the plane as required to smooth, otherwise affect the measurement results.

    The SIM800A Quad-Band GSM/GPRS Module with RS232 Interface is a complete Quad-band GSM/GPRS solution in an LGA(Land grid array) type which can be embedded in the customer applications. SIM800A support Quad-band 850/900/1800/1900 MHz, it can transmit Voice, SMS and data information with low power consumption.

    With a tiny size, it can fit into slim and compact demands of custom design. Featuring and Embedded AT, it allows total cost savings and fast time-to-market for customer applications.

    The SIM800A modem has a SIM800A GSM chip and RS232 interface while enables easy connection with the computer or laptop using the USB to the Serial connector or to the micro-controller using the RS232 to TTL converter. Once you connect the SIM800A modem using the USB to RS232 connector, you need to find the correct COM port from the Device Manager of the USB to Serial Adapter.

    Then you can open Putty or any other terminal software and open a connection to that COM port at 9600 baud rate, which is the default baud rate of this modem. Once a serial connection is open through the computer or your micro-controller you can start sending the AT commands. When you send AT commands for example “AT\r” you should receive back a reply from the SIM800A modem saying “OK” or other response depending on the command sent.

    In terms of the form factor, it looks a lot like the nRF24L01 2.4G RF transceiver. This is a serial module with a built-in TCP/IP stack, so you can use it standalone but you will be likely limited. You need a FTDI to connect this module to your computer, and start communicating with it. FTDI is a common name for USB-to-TTL (or serial) converter.

    The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.
