differ. You can use this to your advantage because it lets you easily convert degrees Kelvin into degrees Celsius. Actually, since your robot will be deciding when hot is hot, and doesn t care what temperature scale is used, conversion really isn t necessary. You can test the circuit by connecting a volt-ohm meter to the ground and output terminals of the circuit. At room temperature, the output should be about 2.98 V. You can calculate the temperature if you get another reading by subtracting the voltage by 273 (ignore the decimal point but make sure there are two digits to the right of it, even if they are zeros). What s left is the temperature in degrees Celsius. For example, if the reading is 3.10 V, the temperature is 62C (310 273 = 62). By the way, that s pretty hot (144 Fahrenheit).

You can calibrate the circuit, if needed, by using an accurate bulb thermometer as a reference and adjusting R2 for the proper voltage. By knowing the temperature, you can determine what the output voltage should be by adding the temperature (in degrees Celsius) to 273. If the temperature is 20C, then the output voltage should be 2.93 V. For more accuracy, float some ice in a glass of water for 15 to 20 minutes and stick the sensor in it (keep the leads of the testing apparatus dry). Wait 5 to 10 minutes for the sensor to settle and read the voltage. It should be exactly 2.73 V. The load presented at the outputs of the sensor circuit can throw off the reading. The schematic in Fig. 34-5 and parts list in Table 34-3 provides a buffer circuit so the load does not interfere with the output of the 355 temperature sensor. Note the use of the decoupling capacitors as recommended in the manufacturer s application notes. These aren t essential, but they are a good idea.
34.5 Firefighting
By attaching a small fire extinguisher to your robot, you can have the automaton put out the fires it detects. Obviously, you ll want to make sure that the fire detection scheme you ve put into use is relatively free of false alarms and that it doesn t overreact to normal situations. Having your robot rush over to one of your guests and put out a cigarette he just lit is a potential values judgment. It s a good idea to use a clean fire-extinguishing agent for your firefighting bot. Halon is one of the best such agents, but is no longer manufactured for general consumption. Alternatives include inert gases (helium, argon) and noncombustible gases (e.g., nitrogen), and they will not leave a sediment on whatever they are sprayed on. No matter what you use for the fire extinguisher, be sure to use caution as a guide when building any firefighting robot. Consider limiting your robot for experimental use, and test it only in well-ventilated rooms or better yet, outside. The exact mounting and triggering scheme you use depends entirely on the design of the fire extinguisher. The bottle used in the prototype firebot is a Kidde Force-9, 21 2 lb Halon extinguisher. It has a diameter of about 31 4 in. You can mount the extinguisher in the robot by using plumber s tape, that flexible metallic strip used by plumbers to mount water and gas pipes. It has lots of holes already drilled into it for easy mounting. Use two strips to hold the bottle securely. Remember that a fully charged extinguisher is heavy in this case over
