+3 Temperature Sensor Support
3-1Q: The document stated supporting DS1822/DS1820 1 Wire Temperature Sensors, I assumed the whole DS18xx family of devices would work. I used a DS18S20+ and get about 3.5 degrees C when powered, 10.6 when parasitic powered. It should read 23-24 at room temperature. For power I tried pin 3 of the temperature terminal and pin 3 of the humidity terminal and the result is the same.
3-1A: WebControl™ can simutanously connect 8 optional DS18B20/DS1822 based digital temperature sensors, as long as the temp sensor is 12bit and non-parasite part. DS18S20 is a 9bit part that only having temperature resolution > 0.5C. DS1822 and DS18B20 are 12 bit temperature sensors. They should work fine. WebControl does not support parasite parts.
3-2Q: How to read temperature or sensor ROM code from command line in Linux?
3-2A: Use wget http://webcontrol-ip/gett1.cgi to read the temp sensor T1, and use wget http://webcontrol-ip/gett1rc.cgi to read the sensor T1 ROM code.
3-3Q: What can cause my temperature sensor not display correctly?
3-3A: It is very possible caused by power supply not providing enough voltage or current. With WebControl connected, please measure your power supply voltage. If that voltage is below 7V, temprature sensor may not get enough voltage.
3-4Q: I run a long cable between the DS18B20 and WebControl, sensor does not work?
3-4A: According to Maxim-IC, if using a long cable connecting between the sensor and host controller, it will require to add a pull-up resistor 4.7k from 1-wire bus (DQ pin on DS18B20) to the 5V supply near the far end of the 1-wire bus. Please check out Maxim-IC AppNote148
