Question

Does anyone know where I can obtain a thermometre or light meter that can be connected to the computer? Mail me. I used to have this neat science toolkit for my old Apple II C which had light sensors and thermometers – you could use them to do all sorts of tricky stuff with (like building a seismometer). The kit was put out by the now-defunct Broderbund software.

Responses:

A light sensitive resistor or diode might be what you want, though I cant say for sure not knowing what you want to do with it.

Try Jaycar, if you have any around Camden… I believe there’s a Dick Smith in Liverpool, Campbeltown and Penrith (from memory… I live in Melbourne though :)

Well I also did a bit of poking around. Vernier makes all sorts of measurement instruments that can be connected to the computer. Lares also does temperature probes. All these were a bit more expensive than I was hoping for… after all, how complex is it to make a device which reports temperatures to a computer? Motherboards can have several temperature and fan RPM headers on them, and they don’t cost $500… (RPM monitors btw, calculate fan rpm by counting the electrical pulses sent through to the fan – I think its two pulses per fan revolution). Hmm… how about Bluetooth enabled thermometers? :)
