If the transmitter is driven by 38KHZ carrier, does the receiver also need to be driven by 38HZ carrier? The receiver uses VS838. If I use a ready-made infrared transceiver module, do you have any rec...
Why is component temperature prediction important? Component temperature prediction is important in many ways. Historically, component temperature has been related to reliability, with early studies c...
I just received it this afternoon, I like it very much. Thank you maylove, thank you EE. I thought I only got one, but I didn't know I got four! I thought the white one in the front was a filter membr...
Calibrators are widely used in university experiments. Among them, there are two experiments in nuclear physics experiments in modern physics experiments (GM counter and β absorption) that require ...[Details]
Although improper medical device product design is not always associated with medical device-related errors. Studies of users have shown that lack of adequate training accounts for 70% to 90% of suc...[Details]
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]
introduction
At the beginning of this century, Veit used Einthoven's galvanometer to record the electrical activity of the human pregnant uterus from the body surface for the first time. In 19...[Details]
The circuit shown in the figure is a three-digit tachometer used to measure low frequency signals with a repetitive time interval of 0.235 to 15 seconds. The tachometer has a speed range of 4 to 255 r...[Details]
