Send your Raspberry Pi sensor data to SAP HANA Cloud via SAP Data Intelligence, trial edition 3.1

[architectSAP]

For more than 3 years, I have been Sending my Raspberry Pi sensor data to SAP Vora via Apache Kafka managed by the SAP Data Hub.

With the availability of SAP Data Intelligence, trial edition 3.1, it was time to upgrade. I chose the deployment on Microsoft Azure:

My Raspberry Pi Zero W gets its temperature and further information from a Bosch Sensortec BME680 sensor now:

Leveraging Python:

#!/usr/bin/env python

import datetime

import bme680

from kafka import KafkaProducer

from json import dumps

sensor = bme680.BME680()

json_body = [

	{

		"millis": str(datetime.datetime.now()),

		"temperature": sensor.data.temperature,

		"pressure": sensor.data.pressure,

		"humidity": sensor.data.humidity

	}

]

producer = KafkaProducer(bootstrap_servers=['your.kafka.server:6667'], value_s

erializer=lambda x: dumps(x).encode('utf-8'))

future = producer.send('bme680', json_body)

try:

	record_metadata = future.get(timeout=10)

except KafkaError:

	log.exception()

pass

Destination is SAP HANA Cloud:

The Graph remained basically the same from when I Restored my NEO Internet of Things Service scenarios with Apache Kafka and the SAP Data Hub:

Running at 1.38M temperature measurements:

The SAP Cloud Appliance Library makes this so easy nowadays.
