The temperature, light reading and status of various Homeeasy switches in my home. The unit is an Arduino with an Ethernet shield. Uptime is in hours since last reboot. The temperature is in °C measured with an I2C sensor with a resolution of 1°C. The LDR reading is from a 10-bit ADC, so 1023 is pitch black, and 100 or less is brig...

Future Arduino Based Garden. Stalled by now!!! testing: 2 moisture sensors, ldr, thermistor and thermohygrometer. sensors are out of calibration by now.. i'm using an asus eeepc to provide internet connection. i wrote a simple linux daemon to read serial line and send environment updates to this feed,i'm using pachulib c library: ...
