Marine Drift Detection System for Water Scooters
A marine safety company needed a compact, waterproof unit detecting unexpected drift on water scooters and alerting the operator in real time. We built a connected device with a 6-axis IMU, GPS, and cellular modem for remote alerts.

Engagement Models
Hire an IoT developer
the way that fits your project.
No forced long-term contracts. Pick the model that matches how defined your requirements already are.
⏱️
Hourly
For scoped tasks, code review, or short bursts of work. Pay only for hours logged, no minimum commitment.
📅
Dedicated Developer
A developer allocated to your project full-time or part-time, working as an extension of your team for the duration of the engagement.
📦
Fixed-Scope Project
Defined deliverables, fixed timeline, fixed price — agreed before work starts. Best when requirements are already clear.
Not sure which model fits? Tell us your project.
We'll recommend the right engagement model on the scoping call — no pressure.
The Freelancer Problem
Why successful Entrepreneurs don't rely on Freelancers anymore
Freelancers often take over 6–8 weeks just to complete a basic IoT project — assuming they stay committed. Hardware delays, no real test setup, and scattered communication slows everything down.
At DigitalMonk, our expert team delivers full IoT solutions within a week, including firmware, connectivity, testing on real hardware, and deployment support.

FAQ
Questions we get
asked the most.
Everything you need to know before reaching out — answered honestly. Still have questions? Just ask.
What does an IoT developer at DigitalMonk actually cover?+
One IoT developer here covers the device side (firmware, sensor integration), the connectivity layer (BLE, Wi-Fi, MQTT, cellular), and the cloud side (dashboards, APIs, OTA). You're not hiring three separate specialists to get a working product. For the broader service overview, see our IoT development services.
What engagement models do you offer?+
Hourly for scoped tasks, a dedicated developer allocated full-time or part-time to your project, or a fixed-scope project with an agreed price and timeline. We recommend the model based on how defined your requirements already are.
How fast can a developer be allocated?+
We respond within 10 hours of your first message. After a short scoping call, we can typically have a developer allocated and starting within a few business days, depending on the skill match required.
How is this different from hiring an ESP32 or Raspberry Pi developer?+
This page is for developers who need to work across the full connected-product stack — device, connectivity, and cloud — regardless of the exact microcontroller or board. If you already know your platform, hire an ESP32 developer or hire a Raspberry Pi developer directly for a more platform-specific fit.
How is this different from hiring an embedded developer?+
Embedded developers focus on low-level firmware, RTOS, and bare-metal work — often without networking involved. IoT developers on this page are specifically for connected products: devices that talk to a phone, a cloud dashboard, or another device over BLE, Wi-Fi, or cellular.
Do you handle both hardware and firmware for IoT projects?+
Yes. Custom PCB design, firmware, cloud integration, and mobile or web apps — fully end-to-end, so you don't need to coordinate multiple vendors.
What does an IoT developer engagement typically cost?+
Cost depends on scope and engagement model. Simple firmware-only tasks start from a few hundred dollars; full device-to-cloud builds with custom hardware typically range from $1,500 to $10,000+. Contact us for a free, no-obligation estimate.
Can you take an IoT prototype to mass production?+
Yes. We design for manufacturing from day one — component availability, thermal management, test points, and production firmware provisioning — and support scaling from 1 unit to hundreds.
Is my idea protected?+
Yes. We sign an NDA before any project details are discussed, and you retain full ownership of everything we build — source code, schematics, board files, and documentation.
