View source for AM2305 DIGITAL TEMPERATURE & HUMIDITY SENSOR

==Introduction to the product ==
AM2305 Digital Temperature & Humidity Sensor is a temperature and humidity combined sensor been calibrated digital signal output. The sensor includes a capacitive sensor wet components and a DS18B20 temperature measurement device and connected with a high-performance 8-bit microcontroller. Each AM2305 sensors are an extremely accurate humidity calibration chamber for calibration. Calibration coefficients stored in the form of a program in OTP memory, internal sensor detection signal processing to call these calibration coefficients. The single-wire serial interface, system integration becomes simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up to 20 meters or more, making it the best choice of even the most demanding applications in a variety of applications then, the product leads to three core shielded cables.

==Configuration Guide==

Before configuring, ensure that the AM2305 sensors are connected to the '''Transight''' telematics device as per the sensor pinout.  
Improper wiring may lead to failed communication or sensor detection issues.
 
<div style="color: red; font-weight: bold;">⚠️ Note: Only one AM2305 sensor can be connected to any Transight device with 1-Wire capability.</div>
 
== Step 1: Enable 1-Wire Sensor Interface ==

This command activates the 1-Wire port for sensor communication.
 
'''Command:'''
<pre>

SET CUENOW:ON
</pre>
 
'''Expected Response:'''

== Step 3: Specify Number of Connected Sensors ==

Define the number of connected 1-Wire sensors (only 1 allowed for AM2305).
 
'''Command:'''
<pre>

SET CUOWNOS:1
</pre>
 
'''Expected Response:'''
<pre>

IMEI: 862942074896044

Command: SET CUOWNOS:1
 
Response:  

Error : 0
</pre>
 
'''Verification Command:'''
<pre>

GET CUOWNOS
</pre>
 
'''Expected Verification Response:'''
<pre>

IMEI: 862942074896044

Command: GET CUOWNOS
 
Response: TEMPERATURE SENSOR NOS: 1

Error : 0
</pre>
 
== Mandatory Finalization Step ==

Apply and save all sensor settings.
 
'''Command:'''
<pre>
SET CUMR:2
</pre>

== Post-Configuration Validation Checklist ==

After configuration:

* 🔄 Monitor incoming device packets.

* 🌡️ Ensure '''temperature''' and '''humidity''' values appear in payload.

* 📈 Confirm '''periodic updates''' from the sensor.

* ✅ Verify '''data consistency and accuracy''' via backend or cloud platform.
