	805	+The SDA and SCK are I2C interface lines. You can use these to connect to an I2C device and get the sensor data.
	806	+
	807	+We have made an example to show how to use the I2C interface to connect to the SHT20/ SHT31 Temperature and Humidity Sensor.

	821	+Convert the read byte to decimal and divide it by ten.
	822	+
	823	+**Example:**
	824	+
	825	+Temperature:  Read:0116(H) = 278(D)  Value:  278 /10=27.8℃;
	826	+
	827	+Humidity:    Read:0248(H)=584(D)  Value:  584 / 10=58.4, So 58.4%

	836	+
	837	+
	838	+==== 2.3.3.8 Ultrasonic Sensor ====
	839	+
	840	+
	841	+This Fundamental Principles of this sensor can be found at this link: [[https:~~/~~/wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU~~_~~__SEN0208>>url:https://wiki.dfrobot.com/Weather_-_proof_Ultrasonic_Sensor_with_Separate_Probe_SKU___SEN0208]]
	842	+
	843	+The SN50v3-LB detects the pulse width of the sensor and converts it to mm output. The accuracy will be within 1 centimeter. The usable range (the distance between the ultrasonic probe and the measured object) is between 24cm and 600cm.
	844	+
	845	+The working principle of this sensor is similar to the (% style="color:blue" %)**HC-SR04**(%%) ultrasonic sensor.
	846	+
	847	+The picture below shows the connection:
	848	+
	849	+[[image:image-20230512173903-6.png||height="596" width="715"]]
	850	+
	851	+
	852	+Connect to the SN50v3-LB and run (% style="color:blue" %)**AT+MOD=2**(%%) to switch to ultrasonic mode (ULT).
	853	+
	854	+The ultrasonic sensor uses the 8^^th^^ and 9^^th^^ byte for the measurement value.
	855	+
	856	+**Example:**
	857	+
	858	+Distance:  Read: 0C2D(Hex) = 3117(D)  Value:  3117 mm=311.7 cm
	859	+
	860	+
	861	+==== 2.3.3.9  Battery Output - BAT pin ====
	862	+
	863	+
	864	+The BAT pin of SN50v3-LB is connected to the Battery directly. If users want to use BAT pin to power an external sensor. User need to make sure the external sensor is of low power consumption. Because the BAT pin is always open. If the external sensor is of high power consumption. the battery of SN50v3-LB will run out very soon.
	865	+
	866	+
	867	+==== 2.3.3.10  +5V Output ====
	868	+
	869	+
	870	+SN50v3-LB will enable +5V output before all sampling and disable the +5v after all sampling.
	871	+
	872	+The 5V output time can be controlled by AT Command.
	873	+
	874	+(% style="color:blue" %)**AT+5VT=1000**
	875	+
	876	+Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
	877	+
	878	+By default the **AT+5VT=500**. If the external sensor which require 5v and require more time to get stable state, user can use this command to increase the power ON duration for this sensor.
