# Integrate with MongoDB
In this article, we will simulate the temperature and humidity data, and publish these data to EMQX Cloud via the MQTT protocol, and then we will use the EMQX Cloud Data Integrations to store the data to MongoDB.
Before you start, you will need to complete the following:
- Deployments have already been created on EMQX Cloud (EMQX Cluster).
- For Professional Plan users: Please complete Peering Connection Creation first, all IPs mentioned below refer to the internal network IP of the resource.(Professional Plan with a NAT gateway can also use public IP to connect to resources)
# MongoDB Configuration
Install MongoDB
# EMQX currently supports MongoDB 5.x drivers, not 6.x yet docker run --name mongo -d -p 27017:27017 mongo:5.0

temp_hum
collection and view the result.db.temp_hum.insert({up_timestamp: 34256, client_id: 1, temp: 20, hum: 33}) db.temp_hum.find()

# Data Integrations Configuration
Go to Deployment Details and click on Data Integrations
on the left menu bar.
Create MongoDB Resource
Click on
MongoDB Single Mode
under the Data Persistence.Fill in the information you have just created and click
Test
. If there is an error, you should check if the database configuration is correct. Then click onNew
to create MongoDB resourceCreate Rule
Choose the MongoDB resource under Configured Resources, click on
New Rule
and enter the following rule to match the SQL statement. In the following rule we read the timeup_timestamp
when the message is reported, the client ID, the message body (Payload) from thetemp_hum/emqx
topic and the temperature and humidity from the message body respectively.SELECT timestamp div 1000 AS up_timestamp, clientid AS client_id, payload.temp AS temp, payload.hum AS hum FROM "temp_hum/emqx"

Check Rules Monitoring
Click the monitor icon of rule to see the metrics
# Test
Use MQTT X (opens new window) to simulate publishing temperature and humidity data
You need to replace broker.emqx.io with the deployment connection address you have created and add the client-side authentication information in the EMQX Dashboard.
