    Hi lads.
    Thought I'd try over here for this. Have a customer looking for mains light sensor with a range of around 30m .
    Any recommendations/sources.?

    You could install more than one PIR, connect them in series and they would cover 30m.

    Alternatively a number of wireless PIRs could be used that are programmed to activate a single receiver. This saves running cables all over the place to get the required coverage. I find the Stinel devices particularly good for this. Although the units are not cheap installation time and the amount of cable required is reduced so much that it results in a net saving.

    Hi. Yes there are many install options. There are many many low voltage units we could use with PSU and relays. The customer is looking for something we can just replace the existing unit with just curious what's available.

    Yup.

    The wireless option is at mains voltage and from memory can switch a resistive load of up to 3 kW without the need for additional relays / contactors / devices. As such it is quite a clean solution.

    There is also a LED floodlight available with the receiver neatly built in.
