Dear All
I am currently working on a project. The project is to design a system that could perform two way data communication in 869MHz band and at the same time system should also be able to perform one way voice communication. I am using RC1280HP module from Radiocrafts to develop this...
No it is a level activated probe, like a simple reed switch inside a magnetic foat that goes up and down to make and release the switch contact. It can be thought of as a simple switch connected to ADC input of PIC with a long about 5meters cable running from switch to PIC input.
Hi All
I am trying to reduce the components in a circuit that is reading the level of fluid probes into ADC of PIC micocontroller. Please see the attached figure for the current circuitry. As shown it is a contant current source of apprx 220uA, Probe is connected between J1 & J3 and data is fed...
@syncopator: does this mean that a minimum of 18.7V (Which obviously wont be the output of 12V reg) is required at the input of LM317 to work? If this is the case then offcourse this circuit wont work as you suggested.
@kcyang: If I connect 3 CMJH180 diodes in parallel at the output of 12V reg...
Very helpful. @kcyang: When you say to limit the maximum charge voltage to 12V, I simulated the circuit by removing the rechargable battery, the output voltage measured in this case was about 0.5V less than input such as 17.5 at output for 18V input of LM317, this means that when I first connect...
Very Comprehensive information. Yes I can connect LM317 input directly to the output of bridge & filter. 14 days is OK as Yuasa would not be used frequently say three times a year for few hours. The question is can this be connected to Yuasa for indefinite period of time without damaging it? 12V...
I am trying to use a 12V DC battery 17Ah Lead Acid from Yuasa with an existing mains operated circuitry. I have attached the circuit diagram that I am trying to implement. Circuit would be operated using mains under normal condition while backup battery is still connected. When operating on...
