The LM35D interface circuit diagram
The interface circuit LM35D LM35D sensitivity of 10mV / ℃, it is up to 1V at 100 ℃ output. As the SF-10 instrument amplifier maximum input voltage of 240mV, so the higher the maximum temperature of the output signal LM35D to be attenuated. Further, LM35D voltage signal is output to ground, it can not directly access the output signal of the two inputs of the SF-10B (the ground pin ⑥, a single power amplifier device can not work), which requires the output voltage decays , and after the transfer circuit voltage to the interface with the SF-10B, as shown in FIG.   (View)

A voice control recording circuit diagram
When a sound wave compression electret microphone MIC, MIC can output a weak audio signal fed from the NAND gate F1, F2, F3 and R3, R4, R5 constitute the three continuous linear amplification of the amplifier circuit , if consider peak waveform distortion , the output signal amplitude F3 has been large enough , after this signal is coupled through C4 by D1, D2 rectifier get unipolar pulses C5 charging. VC5 soon more than 1/2VDD, the output of NAND gate F4 0, F5 output is 1 , high charge to C8, VC8 also soon be greater than 1/2VDD, F6 output is 0 , the transistor T saturated conduction , SCR is trigger , so 220V mains supply via socket CZ to the recorder , recording starts ; If the sound disappears, the C5 voltage can not be maintained , VC5 quickly dropped to zero. Similarly , C8 only slowly discharge to R8, VC8 about three seconds after the drop to 0 , then , SCR deadline , tape recorders recording aborted ; so, automatic recording control recording ( if necessary delay longer available appropriate to increase the capacity of C8 ) . This control circuit is not only used for automatic recording recorder can also be extended to other appliances require intermittent voice, interested friends can do it. If the sensitivity is not satisfied, it can be in F1 before adding a transistor amplifier.   (View)

Hardware schematic circuit
Hardware schematic is shown in Figure. This is an evaluation circuit, which can install three digital temperature sensor: AD7414, AD7416, AD7814, the software displays each device in turn measured ambient temperature and OTI analog outputs with LED indication. Some explanations are now as follows: (1) address of each device is different, and SDA, DOUT leads can be connected directly; AD7414, OTI output line (active low), now overrun alarm indication for the AD7416. (2) due to the inertia of the temperature coefficient of the larger, can be a simple and effective method of moving average, median method, low-pass filtering method for software filtering. In practical applications, the side of the sample side, the average of the average value as the temperature samples. Sampling frequency of 8 to 16 times can be. (3) The system uses LCM103 LCD module for temperature display, X25045 for power-on reset and watchdog with.   (View)
