Check battery voltage before the charge and after overnight charge. Your right about the 8 volt charger. You can use an automotive charger but will have to watch that it does not overcharge the battery. The 12 volts on 8 volt will charge it, but the best would be a 24 volt charger, where you could charge 3 at a time.
A high accuracy electronic cold junction compensation circuit maintains typical system accuracy of Â±0.2Â°C over an ambient temperature range of 15 to 35Â°C. Individual offsets may be added to each input in software to facilitate individual calibration of each channel. For information on our wide selection of Type T Thermocouple temperature probes.
SEN-00245 RoHS. Description: This is the latest DS18B20 1-Wire digital temperature sensor from Maxim IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus.
