The RW1820 temperature sensor, processed in a stainless steel housing and extended with a cable of about 100cm.
The RW1820 sensor is largely compatible with the DS18B20 sensor. We have explained the main differences in the table below (based on the datasheet):
|Voltage range||+2.8 - + 5.5V DC||+3.0 - + 5.5V DC|
|Accuracy(-10°C - + 85°C)||±0.5°C||±0.5°C|
|Accuracy(+ 35°C - + 45°C)||±0.5°C||±0.5°C|
|Temperature conversion time||80ms||750ms|
|Optional resolution(faster conversion)||7 - 12 bits||9 - 12 bits|
|Ability to calibrate||Yes, via "OTP"||No|
|"Parasite power mode"||Yes, with 10nF capacitor between Vcc and ground||Yes, no external components required|
Explanation "parasite power mode":
The RW1820 has no built-in capacitor without external components in the "parasite power mode" to be able to work. This can be done by adding a 10nF capacitor over the Vcc and ground. We also tested this and got it working with a 100nF capacitor. Make sure that you do not short-circuit the Vcc and ground pin as you would have to do with the DS18B20 in "parasite power mode". With the RW1820 you only need to connect the ground, datapin and capacitor between the Vcc and ground pin. Also note that the function"Read Power Mode", command "B4h" does not give a correct result. The RW1820 always gives a high signal as described in the datasheet on page 13 and as our tests also show.
