MongoDB query for Sensors Data Collection

I have Current measuring Sensor and wants to send sensors data Based on room_no in MongoDB.

I have Room 1 Schema in Nodejs for MongoDB 

var Sensor_Schema = mongoose.Schema            //sensor_data schema

({
    room_no: [{type:String, "default":''}],
    current:[{type:String, "default":''}],
    power: [{type:String,  "default":''}], 
}, 

{
    versionKey: false
});

I need help in MongoDB query for sending data based on room_no. I know i have to use aggregation but unable to understand how can i use it.

Below is the sample that looks like for storing sensors data. I hope this will help you

aggregate([{$group :{_id: "$room_no", pwrarr: {$push: "$power"} , crntarr : {$push:'$current'}}}])

PS:here pwrarr and crntarr are arrys
