HWg-WLD Relay detects a water leak anywhere along the length of the connected sensing cable (2+2m – 6.5+6.5ft). Water leak or cable disconnection is indicated by activating a relay (NO/NC). The sensor can be connected to a Poseidon unit over the 1-Wire UNI bus (RJ11).
HWg-Juno is an I/O device for IP CCTV integration. You can simply connect digital inputs & relay outputs to your current central IP video management system. HWg-Juno support protocols for seamless integration with most IP Video software packages.
Protection against electrostatic discharge is rapidly increasing in importance. This article provides an overview about what ESD is, where does it come from, and how can you protect your circuits from it.
You can use several programming languages for developing the applications based on x51, such as ASM, C, Pascal, Basic and so on. More than 50% of developers are still using the classical assembler language, but this is going to change. Today’s trend of the MCU programming is the use of higher programming languages such as C.
If you are going to invest more than a small amount of money, you have to decide what the tool is going to be used for. If you are just choosing the right compiler, pay attention to the following things:
Very often, data needs to be transferred from a PC to another, either a notebook or a desktop model. Without a network, only the serial or parallel ports can be used for direct-connect data transfer. This article covers the often forgotten parallel port.
As a preface, I would like to say that HW server does not indend at all to 'criticise at every cost'. We do our own development, too, and we do understand that it is not that easy to design and document something. However, we think it necessary to inform our readers about fundamental faults and errors of electronics components that can cost a lot of time.
