Thermistor help need

19 May 2012 - 05:42 PM

Hello, I have a NTC thermistor R(25C):10kΩ - Β(25C/50C):3950. I am trying to convert the readings of Analog0 into temperature. If I use AnalogInput.Read I get values from 0.0 to 1.0 If I use AnalogInput.ReadRaw I get values from 1 to 3000 I connected the thermistor using voltage divider like : GRD --- Resistor 10KΩ --- Thermistor --- 5V ...................................| ...................................| ..........................NetGo Analog 0 Please help, Thanks.

NetduinoGo - PC Serial Communication

18 May 2012 - 09:41 AM

Hello there, I wonder if there is a way to serial communication from/to PC - NetduinoGo. I am planning to write a windows app to send some strings or boolean values to Netduino in order to open/close relays. Can NetduinoGo send values to serial comm port ? Do I need a special board to do it ? eg convert Rx/Tx to USB ? Thanks.

Netduino Temperature Monitor Project

08 May 2012 - 06:21 PM

Hello, a friend of mine is asking to build him a project in order to check the temperature of 3 (big) refrigerators. We want to do the following : - The system must monitor the three temperature sensors and when it exceeds a specific value it must send an SMS to a mobile phone as a warning. - We also want the system to be able to accept SMS messages and send back the value of a sensor Can you please help me picking up the correct hardware for netduino go ? I obviously need a GSM Module and three temperature modules. I have already ordered an netduino go board, some cables and a shield module. I am quite new to electronics but I have a background in .NET and mostly VB.NET Thanks.-
